[NTG-context] \startstaticMPfigure
From the Wiki I learn about \startstaticMPfigure that it creates a separate
pdf file containing the graphic. But when I exercise the example given I do
not see those staticMPfigure's in sepaarte pdf's. What am I missing? I thought
to use this for generating a series of separate pdf's, to be further processed
as png/tiff files.
\startstaticMPfigure{center}
draw fullcircle scaled 2cm ;
dotlabel.bot (textext((0,0)),origin);
\stopstaticMPfigure
\startstaticMPfigure{radius}
draw fullcircle scaled 2cm ;
drawarrow (0,0)--(1cm,0);
label.bot(textext($r$),(5mm,0)) ;
\stopstaticMPfigure
\starttext
Circle centered \usestaticMPfigure[center][width=1cm] at origin with radius
\usestaticMPfigure[radius][width=1cm] $r=1\,\text{cm}$.
\stoptext
By the way, is transparency still working as in the wiki example below, or has
transparency vanished?
\startreusableMPgraphic{a}
fill unitsquare scaled 1cm withcolor yellow;
fill unitsquare shifted (0.5,0.5) scaled 1cm withcolor transparent (1,0.5,red);
\stopreusableMPgraphic
\placefigure[force,none]{}{\reuseMPgraphic{a}}
Thanks in advance

[NTG-context] MetaPost visibly drawing at 0pt
I used to put an invisible frame around figures in MetaPost by setting a pen scaled at 0pt. That left no trace, but defined the area. However I (now) see a thin line drawn by code: pickup pencircle scaled 0pt; draw origin--(w,h); Did I always mis this or has something changed? For example a roundoff away from zero in MetaPost?

[NTG-context] colon in lucida math
I get the impression there is something wrong with typesetting math with the
lucida setup in ConTeXt. I find that the \colon is not printed. Below is a
minimal example. See the colon in the first formula that is absent in the
second.
Perhaps someone is willing to check if this is ConTeXt in general or my own
setup in particular. In both cases I will be pleased with a remedy.

[NTG-context] bibmodule acquired problem
I used the following macro for typsetting literature references in footnotes.
It worked without problems until now, but then I didn't use the bib module for
some time.
It looks like a problem has crept in with the inproceedings type.
the macro setup:
\usepublications[literature]
\setuppublications [alternative=apa]
\setuppublications [numbering=short,refcommand=data]
\setuppublicationlist [%
editor=\normalauthor,%
author=\normalauthor,%

\def\bibentrypar{\def\bibentrypar{\par}}%
\unskip\footnote{\processcommalist[#1]\bibentry
\doifnotempty{#2}{\bibentryspace#2\strut\par}} }
It fails for the following entry:
\startpublication[k=campbell:92,t=inproceedings,

Re: [NTG-context] postion graphics
Thanks. But after having a closer look I decided to abandon the mechanism. It
looks fairly sophisticated: finding positions in the TeX-result and producing
overlays for them. Because I used it solely inside table-like structures for
pointing from one cell to another, I can replace them by MetaPost pictures. It
seems more robust that way. So you do not need spending your time on it.

Re: [NTG-context] bibmodule acquired problem
Step by step I am able to dig deeper in the problem. The fact that it used to
work but now doesn't may well be connected with the fact that the booktitle in
those cases came from a crossref = item in the bib file. Could it be the
\crossref{} macro is not recognized any longer by the ConTeXt bib module?
In file bibl-tra.mkiv I encounter the following comment:
%D \macros{bib@crossref}
%D
%D \type{\crossref} is used in database files to point to another
%D entry. Because of this special situation, it has to be defined
%D separately. Since this command will not be seen until at
%D \type{\placepublications}, it may force extra runs. The same is
%D true for \type{\cite} commands inside of publications.
In typesetting the citation in the footnote I am solely using cite, not
\placepublications.
Does someone know why earlier the \crossref worked and now obviously has been
switched out of the loop?
Is there another way to force these crossref's to be carried out?

Re: [NTG-context] bibmodule acquired problem
Yes, we are having the two faces same problem, I guess.
The fact is that \booktitle in the crossref'ed publication should be processed
as a \title item in the citatation crossreff'd. The error in my case boils down
to the fact that the title-entry is called without being actually present.
With the missing \title sofar I have nailed it down to macro \bibgetvart#1 from
the following bbl entry:
\startpublication[k=campbell:92,t=inproceedings,
a={{Campbell},{Wiener}},y=1992,
.. (no \title)
\stoppublication
and log printing in the log from the modified macro:
\def\bibgetvart#1{\writestatus{ERROR}{Parameter #1 on bibgetvart
\expandafter\string\csname pbd:#1\endcsname}\csname pbd:#1\endcsname\plussix}%
I find the log:
ERRORParameter campbell:92 on bibgetvart \pbd:campbell:92
ERRORParameter on bibgetvart \pbd:
! Missing \endcsname inserted.
Thus the missing \title thus seems to result in extra call to a bibliography
entry that does not exist.
This is about as far as I am at the moment in analyzing the problem.

I can see that \bibinsertcrossref gets the proper reference because the defined

Experimenting on \bibinsertcrossref (inside \unprotect-\protect):
Redefine \def\bibinsertcrossref#1#2#3{\cite[crypto92]} CITE WORKS!
But redefine: \def\bibinsertcrossref#1#2#3{\cite[\@@pb@crossref]} CITE GIVES AN
ERROR
The redefine:
\def\bibinsertcrossref#1#2#3{\edef\tmp{\@@pb@crossref}\cite[\tmp]} CITE WORKS
Therefore I propose to change the definition of \bibinsertcrossref to:
\def\bibinsertcrossref#1#2#3{\bibdoifelse\@@pb@crossref{\edef\tmp{\@@pb@crossref}#1\cite[\tmp]#2}{#3}}

Maybe the problem is already present for so long. It occurs only if title

Re: [NTG-context] usepath?
This didn't work for me. I guess it has to do with some misunderstanding about the directory from where projects start reckoning. The directory structure is: directory-project directory-project/product (context runs from here) directory-project/product/component-a-subfiles directory-project/product/component-b-subfiles Code in directory-project/product/component-a-subfile does \input but cannot find files in directories below or in directories alongside.

I have the following code:

\startMPpage

\stopMPpage
\stoptext
Replace the \readfile by:
\input ../../../metapost-setup %(file with metapost inclusions)

But with \readfile seems to be skipped silently, that is without any sign of it
in the log. The convenience of \readfile should be, if I understand correctly,
that it searches upwards to the root of directory tree. Which makes the series
of ../'s unnecessary and allows for easily pushing the tex-files further down
when their number grows.
Can it be explained?

Re: [NTG-context] readfile not understood
Finding the file works with \ReadFile{} works. But is generates another problem
because
\input ../../../metapost-setup
and
\ReadFile{metapost-setup}
behave differently! The \input process my \startMPinclusions correctly but the
ReadFile does not, because the following metapost has the definitions missing.

\readfile expects three arguments, replace it with \ReadFile which expects

Can you provide a minimal example. I don't get any extra spaces
\enablemode[test]
\starttext
A\doifmode{test}{B}C
A\doifmode{notest}{B}C
\stoptext
There is a unwanted space in the second paragraph.
I dare voicing a different opinion. Allthough there indeed is both a space
before the \doifmode as well as after it, I am aware of that but that is
besides my point. I expected the \doifmode to vanish completely when the
condition is not met. As is the case, even if the condition is not met it has a
measurable effect because of the extra space being typeset.
To be more explicit, my expectations were: A \doifmode{condition-not-met}{B} C
resulting in: AC
whereas it becomes: A C.
\enablemode[test]

A \doifmode{test}{B} C
A \doifmode{notest}{B} C

Re: [NTG-context] \startmode and \ignorespaces
I made an example of the effect of this on \doifmode and \startmode. The
example shows that the appearance of extra space in \doifmode follows a regular
pattern. The startmode case differs in that respect because
\startmode[condition-true] has the extra space but \startmode[condition-false]
has not. In my view that is an unwanted anomaly. A little redefinition remedies
that as can be seen in the example.

some text\doifmode{xyz}{ conditional text} following text

With regard to this it is understandable and correct that extra space is
taken in the next construct:
some text \doifmode{xyz}{ conditional text} following text.
But it looks different to me when using the \startmode .. \stopmode pair.
some text.
\startmode[xyz]
some conditional text.
\stopmode

In order to avoid here the extra space one has to code an extra %
some text.
\startmode[xyz]%
some conditional text.
\stopmode
further text.
or (not preferred imho):
some text.%
\startmode[xyz]
I think this is error prone as it is al too easy to forget the %. The
situation here differs from the \doifmode-case. I tend to believe that the
fact that the \startmode[] .. \stopmode construct invites one to separate the
statements with newlines (whitespace thus). Therefore I would ask if this
plea for an \ignorespaces effect at the end of the \startmode[xyz] should be
honored.

The module serves also as replacement for the fixme module where it is necessary to take care that no extra spaces are added when the text is hidden. Wolfgang, Thanks for your reply, but I find it takes a sidetrack and does not answer the question. Please let me explain. It might well be that the annotation module does something of the sort, but that is not my point. The mode-mechanism is explicitely given as a means to do conditional typesetting. If I may cite from the wiki: Very often, you want to generate multiple versions of the same document: one version for printing and one for viewing on the screen, one version for students and one version for the instructor, and so on. .. Or you could use modes - the ConTeXt way of doing conditional processing Well, that is exactly what I want to do and I fail to see why another module (like annotation) should be necessary. Therefore, please do not keep pointing me to something that in my opinion is not needed in this case and is already fully provided for in ConTeXt. When I am pointing out something that I think is an anomaly in the behaviour of ConTeXt or probably not intentional, it is not meant as criticizing. To the contrary, my intention is always to make a constructive contribution. Your reply however is not an answer to the question I brought forward. It might be that there are reasons for not changing ConTeXt in the manner I proposed on this issue. I can live with that, because I have no role in the development. But I think it is legitimate to ask why that decision is made. I am certain you will understand this.

context arguments=key1=value1,key2=value2
or
context arguments=key1=value1,key2=value2
or otherwise
(2) how are these values picked up inside the TeX-run for use in typesetting?

Re: [NTG-context] arguments on context call
Thanks,
I was already trying to jump through the hoops of \ctxlua, but this is really
simple and exactly what I needed. The offline calls to context/metapost figure
production now can get all the information needed to synchronize with the main

Re: [NTG-context] metapost question
Peter, Thanks for trying to help. Because I solved the problem in another way you might be interested or even benefit from it. The underlying problem was drawing a border around a picture of given dimensions. The border being either colored or left uncolored. The border color should come from a withcolor modifier, with the uncolored case done simply by leaving this out, for example: borderinsideframe(u,v,2g); and borderinsideframe(u,v,2g) withcolor red; It turns out this can be done with an unfill. I learned that a bare unfill erases, but add a withcolor modifier and the effect is a coloring. Thus the trick is: def bordercolorframe (expr w, h, off, clr) text modifier = unfill (-off,-off)--(w+off,-off)--(w+off,h+off)--(-off,h+off)--cycle modifier; fill (0,0)--(w,0)--(w,h)--(0,h)--cycle withcolor clr enddef; The omission of a semicolon after the last statement of the def allows one to add in a withcolor somecolor without triggering an error. Hope this will be of use to someone.

[NTG-context] color and textext
After some struggling with text colouring in metafun I finally encountered on
the wiki:
Another difference is the way text is handled in mkiv. In particular, color
(withcolor) is not applied to metapost text. For example,
draw thelabel(decimal i, (i, 0) scaled 1cm) withcolor red ;
currently does not work in mkiv. However,
label(textext(\color[red] decimal i), (i, 0) scaled 1cm);
does work. This second solution works both in mkiv and in mkii. (Note that
\color[red] can be abbreviated \red.)
My question: is currently in currently does not work in mkiv in fact
permanently or will this restriction soon be lifted? If the restriction is here
to stay, I will have to find a workaround for my label-typesetting code in
metapost.
Or perhaps someone can tell me how to make textext use a color existing in
the metapost world. That would work as well.
Explaining my setup:
The colors are taken up in metapost with
def defineColors (expr outlineColor, …) … outlinecolor_ := outlineColor …
enddef;
which is called in ConTeXt as …(\MPcolor{aColor}…
But I do not know how to transform the \MPcolor{aColor} back into a form to be
used as for example
textext(aColor…

[NTG-context] macro string in metapost
The goal is to make the following string in metapost:

s := MPcolor char oct134 char oct173 Blue char oct134
char oct175;
But I seem unable to add a \ in front of it without expanding the string by
TeX. Thus it does not work to put:
s := char oct134 MPcolor char oct134 char oct173 Blue
char oct134 char oct175;
Placing a \noexpand in front does not help.

Re: [NTG-context] terrible png placement
Sofar I received 2 reactions.
(1)
Can't reproduce here; I get a 70KB pdf with your file and image.
ConTeXt standalone, 32-bit Linux, mkiv, version 2011.10.01 10:48.
(2)
I've encountered the same problem. The PDF is 1.8MB big. Compressed with qpdf
(qpdf --stream-data=compress) its only 60KB!
Latest beta on OS-X 10.7.2
Further search for the cause:
My system is also OS-X 10.7.2 and latest beta.
To find the culprit I reverted to an older version of ConTeXt.
ConTeXt ver: 2011.10.14 22:47 MKIV fmt: 2011.11.11 int: english/english
Now the filesize becomes 72KB instead of 1.8 MB.
This one seems OK.
CONCLUSION: This must have been introduced in one of the beta's later than
2011.10.14 and in or before the current one: ConTeXt ver: 2011.11.04 14:15
MKIV.
I kindly suggest Hans takes a look into the matter.

Re: [NTG-context] extra white after equation
I guess I have found the culprit in the bad placement of formulas without an
equationnumber.
The minimal example I used is that found in strc-mat.mkiv, added a [-] in the
middle one.
\setuppapersize[A6][A6]
\setupformulae[spacebefore=0pt,spaceafter=0pt]
% HERE REDEFINED \dododoformulanumber

\placenamedformula[one]{first} \startformula a = 1 \stopformula \endgraf
\placeformula[-] \startformula a = 2 \stopformula \endgraf
\placenamedformula {second} \startformula a = 3 \stopformula \endgraf
\stoptext
It appears that in the case of an absent equationnumber extra stretching takes
place at the position of the (now absent) equationnumber. Placing phantom ()'s
remedies this. The effect is best seen by enabling the
\rlap{\tracedformulamode}%-line.
May I ask Hans to take a look and change it in the next beta if this indeed a
correct solution? For my suggestion for the change see below.
Thanks in advance.

Re: [NTG-context] referencing

introduced the unskip in order to remove the space that ruins the end of a line

period would otherwise acquire a space before it.

[NTG-context] equation numbering

Now I change the call to \placeformula[equ:thisfml]\startformula..\stopformula and the number changes to (1.6). Why is this? What I have in mind is to number all formula consecutively with (chapternumber.1), chapternumber.2) etc. Regardless whether I want to reference some of the equations later on and some can stay without a reference because that is not needed. Nevertheless, the ascending numbering pleases me.

The link works when the code above is placed BEFORE \completecontent. But
becomes incative when put BEHIND it. The index however has links

Please can some enlighten me? Why are links through \placefigure,

[NTG-context] captions trouble

with numbered labels, but now and then a figure without. First I thought to use
[location=none] on the placement, but then the numbering is not interrupted:
label-1 (label-2 invisible), label-3. That is disturbing to the reader who will
think a figure is missing. The numbering and the label are suppressed by
\setupcations[number=no] and reinstated with \setupcaptions[number=yes]. But
this kills the space between the label and the caption. I enclose a minimal
example that shows the effect. Could this be a bug?

I could not make a twoline text with textext(abc\crlf xyz,pos), it comes

Is it a feature or a defect?
textext(...) is a hbox. So you need to either use
textext(\vbox{... \crlf ...})
or
textext(\noexpand\framed[align=normal]{... \crlf ...})

It's described in Layouts in context. There are plenty of schemas for

Hi,
I uploaded a new beta. As I'm still in cleaning-up mode, the usual problems
could show up as quite some code was adapted (moved around). For those
interested there is a file 'status-mkiv' that can be run to get an overview
of where we stand.
One big change has been the way alignments are initialized. There were two
methods (one for \setupalign and one for align keywords) and these have been
merged into one. A side effect is that an alignment change is twice as fast
as before which might make a difference in excessive usage of \framed and
some table mechanisms.
Another change is that \color[whatever]{} now always expects an argument (in
\MKII {\color[red] ...} is valid too. Some more commands might get that
restriction but not the style switchers etc). Again this is twice as fast as
the previous method (probably not that noticeable as many switches happen
otherwise).
For those who won't/didn't get it by snail mail .. this years card can be

[NTG-context] searching xml node tree
In the processing of xml data path expressions like a/(b|c)/*/d etc. can be
used.
However, I have a node that can be present inside every node of the tree.
One method to collect these all together is bij successive calls:
\xmlall{#1}{/node}, \xmlall{#1}{/*/node}, \xmlall{#1}{/*/*/node}, etc.
But that fails if the tree is deeper than foreseen.
I tried recursive searching within the node-setup-processor by calling
\xmlall{#1}{../*/node} but either this fails or I am not doing it the right way.
Any ideas?

[NTG-context] strip space in xml
I have the following problem with xml processing. Spurious space is typeset,
annoyingly visible when nearly equivalent structures are typeset one under
another.
Take the following node structure where the text node is the one intended to
contribute to the typeset material, whereas anothernode is not.
root
node
anothernode../anothernode
text
..
/text
/node
/root
Doing in the root-node: \xmlstripnolines{#1}{/node}\xmlall{#1}{/node} removes
some of the unwanted spaces but not all. Especially the space between
/anothernode and text does not completely disappear (seen with
\xmlstrippednolines).
This also occurs when /anothernode and text are on the same line separated
by a number of spaces.
The space disappears when /anothernodetext are put next to another.
However, this destroys the neat typography of the xml.
The manual tells me that \xmlstripnolines ..collapses embedded spaces from
nodes under node.. That seems correct in that obviously the code leaves one
space from the intervening spaces/newlines.
But this gains me nothing! Why leaving a single space between node and
next-node? For me this defeats the purpose of xmlstripnolines.
Can this be remedied?

Re: [NTG-context] missing macro
In the meantime I have looked further into the problem. Although in the past redefinition of \Word was the only way to repair, this time there was a destructive interference with \startframedtext. It turned out that \startframedtext[align=middle, etc.] played havic with the following input, to the effect that \Word didn't work as expected. The simple solution --after some digging into my notes inside my (very) old copy of the ConTeXt manual-- was to always put the first set of brackets (even if empty) on the start: \startframedtext[][align=..] etc. Then the problem goes away, but I keep my fingers crossed ;-) No cause for calling bug therefore.

Re: [NTG-context] include file in xml processing
I have seen that I can load a file (containing ConTeXt code) with
\startxmlsetups xmlcommon:texinclude
\writestatus{TEST HVDM}{file: \xmlatt{#1}{file}}
\xmlload{#1}{\xmlatt{#1}{file}}
\stopxmlsetups
But how to use these loaded data? I want them included in ConTeXt-processing
like this but it doesn't work:
texinclude file=filename/
tex
\useMPgraphic{xyz}{param=285}
/tex
The tex node is just a wrapper around \xmlcontext{#1}{.}
Someone who can put me on the right track?

Since I need some MetaPost drawings repeatedly I thought to include those from
a separate file:
tex
\input thedirectory/thefile
\useMPgraphic{lfsr}{stages=285}

The file is read, but typeset as is, MetaPost processing does not occur. By the
way, inserting the MetaPost code in place of the \input works ok.
I also tried \usemodule[thedirectory/thefile] instead, but then nearly
everything MetaPost encounters is undefined.
Does someone know how to get the file inclusion right?

[NTG-context] overfull hbox on items

align=right,itemalign=flushright,
stopper={.\,}

In the logfile: Overfull \hbox (3.0pt too wide) detected at line 7
Changing to distance=4pt makes the hbox 4pt too wide.
Changing to distance=0pt (or delete parameter) makes the hbox fit.
Why is this?
Apart from cluttering the logfile, I guess this hbox overflow signals something
that can be bettered.

There is something in the processing of mathml I do not understand.
I keep the xml-node in a
\startxmlsetups my:setup
\def\mynode{#1}
\stopxmlsetups
Doing \xmlflush{\mynode} does typeset the contents of mynode, but not when
mynode contains a mathml tree! Then the error is:

\par \let \par \relax \everyvbox {\let \par \MMLpar }

Tested it with a simple:
math xmlns='http://www.w3c.org/mathml' version='2.0'
applyroot/ ci x /ci /apply
/math
The strange thing is, when putting the mathlml tree insize text
mathml-content /text where:
\startxmlsetups xam:text
\xmltrim{#1}\par
\stopxmlsetups
then typesetting goes without an error!

[NTG-context] xmlinclude
Can someone tell me what \xmlinclude is supposed to do? I have experimented a
lot but didn't come further to an understanding.
I have called it through:
\startxmlsetups xam:include
\xmlinclude{#1}{include}{file}
\stopxmlsetups
from a node include in:
probleminclude file=functions.xml//problem
and indeed \enabletrackers[lxml.loading]gives me in the log:
xml tex loading file './xm-test-problem.xml' as 'problem'
But then nothing seemed to have happened. The xml-node in that file is never
seen. I checked that by listing all these nodes in the log
(\xmlcommand{\xmldocument}..)
The include and others are listed, but not the contents of the file I thought
I had included.
Clearly I have some misunderstanding here as to what the manual implicates. It
states:
\xmlinclude{node}{lpath}{attribute} includes the file specified by attribute
of the element located by lpath at node node.
I take this 'node' ast the node from where the lpath is rooted, but I might be
mistaken.
And most of all: what happens to the included file and how can I approach/use
its contents?
I would appreciate an enlightment. Thanks in advance.

[NTG-context] getting xml instead of context
In the processing of incoming xml-data this is typeset as is, not as processed
text.
Thus for example: with \xmlflush{#1} the incoming data:
textits_content/text is not typeset as: its_content, but as:
textits_content/text.
Substitution of \xmlcontext{#1}{.} for \xmlflush{#1} makes everything go away.
Allthough my program is a bit too long to present here, a minimal example is
the application of \xmlstripped{#1}{.} instead of \xmlflush{#1}; it has the
same result.
The output below shows how things looks and clarifies the issue; see the second
answer of the multiple choice.
How to process these data to neatly typeset material?

[NTG-context] xml error
lxml-ini.mkiv defines:
\unexpanded\def\xmlregisteredsetups
{\xmlstarttiming
\xmlflushsetups
\xmldefaulttotext\xmldocument % after include
\xmlstoptiming}
but \xmlflushsetups can be found here only, nowhere else in the ConTeXt
base-files does a search for it match. Calling \xmlregisteredsetups results in
an error:
Undefined control sequence
\xmlregisteredsetups ...arttiming \xmlflushsetups
\xmldefaulttotext \xmldocu...
What could have happened to the xml-modules? As there seem more problems with
it then this one alone.

[NTG-context] xml manual typo
I am reporting a typo in the MKIV XML-manual. It can put one on the wrong track.
Section 3.7 Setups:
\xmlsetup{name}{node} expands setup name and pass node as argument
Note that name and node in the parameters are interchanged.
It should read:
\xmlsetup{node}{name} expands setup name and pass node as argument

Re: [NTG-context] howto execute loaded xml?
It took hours (some far in the night) to solve. Finally. I am posting this
message just in case someone starts delving into it.
Still standing is the problem of \xmlcommand not obeying the attribute
selection but generating an error:
\xmlcommand{#1}{path[@attrib==whatever]}{command}

I made a minimal example showing that load'ed xml is not typeset. In contrast
to the first text-node the second comes out as xml and not as typeset text.
What has to be done to change that?
Thanks in advance.

I was not aware of that problem. Indeed, the greek lowercase appears with \setupbodyfont[postscript]. But not with the brandnew \setupbodyfont[lucidaot], which is quite a nuisance.

Can it be remedied with a more generic mkiv solution? - you can define a combined font that gets greek from a math font - you can define a conversion that takes greek from a math font (the second one could then be hooked into the 'g' option) I see, although I have not the faintest notion how to accomplish that.

[NTG-context] \xmlcontext inoperative?
Loaded xml with: xmlinclude{problem}{include}{file}
Then called up parts of its contents through a setup:
\startxmlsetups xam:define:get
% The definition is the one with content.
\xmldoiftext{#1}{.}{
\foundtrue
\xmlflush{#1}
\xmlcontext{#1}{.}
}
\stopxmlsetups
The strange thing is that the \xmlflush typesets verbatim the contents of the
node called up:
math version=2.0 xmlns=http://www.w3c.org/mathml; apply eq/ ci f(x)
/ci apply plus/ ci 1 /ci apply power/ ci x /ci ci 4 /ci
/apply apply power/ ci x /ci ci 7 /ci /apply /apply /apply
/math
but, to my surprise the \xmlcontext{#1}{.} lets it disappear completely. So
does \xmlflushcontext{#1}. In other parts of the program \xmlcontext does what
it should do, thus the mkvi format seems ok.
What could have happened? Some detrimental effect of the \xmlinclude?
