Hi,
please find below a proposal for a XML-FAQ format. I hope it covers
all suggestions Hans and Henning have made in the last discussions.
More suggestions are welcome.
notes:
- the label= in <contextfaq> can be used for cross-references
- the id= in <author> is a reference to the author database as
requested by Henning
- the modified= in <revision> should be used to highlight updated
FAQs in a new ConTeXt-FAQ issue
- there is only one key for sectioning, since IMO the "application"
should know where this section (specified by id=) is in the
document tree. This should allow easy reordering of the FAQ
- and a question: what is the better solution for different types
of parenthesis in TeX code; the 1st or the 2nd <texcode> block?
Tsch� Jens.

<question>
Is it possible to show only a part of an external figure?
</question>
<answer>
<p> The command <tex>clip</tex> allows to show only a part of a figure.
You can either split the figure in rows and columns in order to show
one
of the resulting segments or you can specify a viewport directly.</p>
<p>The following code tiles the figure in 3 columns and 2 rows and
shows
the segment in row 1 and column 2:</p>
<texcode>
<macro>clip</macro>
<sqbracket>nx=3,ny=2,x=2,y=1</sqbracket>
<braces>
<macro>externalfigure</macro>
<sqbracket>yourfigure</sqbracket>
</braces>
</texcode>
<p> In order to specify the visible part directly you can use:</p>
<texcode>
<macro>clip</macro>
[hoffset=3cm,voffset=2cm,width=4cm,height=3cm]
{<macro>externalfigure</macro>[yourfigure]}
</texcode>
