Just to provide more information about what I was thinking:
You do your typesetting based on an XML doc. Now it is time for the finishing
touches. In a tex document you'd add the usual commands to manipulate the
layout:
\adaptlayout[lines=+1]
\testpage[3]
\looseness=-1 / \looseness=+1
\blank
\setuptolerance
etc.
Now, of course you can define an injector for these commands, some are
predefined, like page, column, blank.
But, if my understanding is correct, you'd have to define one for each of the
possible parameters.
So, you'll need:
\startsetups xml:directive:injector:testpagethree
\testpage[3]
\stopsetups
\startsetups xml:directive:injector:testpagefour
\testpage[4]
\stopsetups
etc., and
\startsetups xml:directive:injector:addoneline
\adaptlayout[lines=+1]
\stopsetups
\startsetups xml:directive:injector:addtwolines
\adaptlayout[lines=+1]
\stopsetups
Here, I was thinking if something like this could be easier:
<?context-directive raw-tex-injector \testpage[4]?>
Wolfgang's solutions seems to provide that with different means. If I
understand correctly, you'd just map an arbitrary XML element to this setup,
and you can then do this:
<rawtex>
\testpage[4]
</rawtex>
Correct?
If yes, that would be a nice solution, but those elements are probably not
allowed if your document needs to be validated against a schema, yet processor
instructions will be ignored during validation.
Any ideas for alternative approaches? What do you think about a raw-tex
injector? (Another possibility would be to use Wolfgang's suggestion, and then
to use an XSLT stylesheet to remove those illegal nodes for validation
purposes...)
Best,
Denis
