A leftover from merging two documents.
Once should be sufficient.
I’m not sure if it was a good idea to use german names for the elements.
Using english names and making the language configurable may be the next step.

Right, I startet out \xmlflush{}ing everything and turned it into \xmltext later.
I missed this one.

Great, it works now.

I want to add
<docan>\xmltext{#1}{../../pverantwortlich}</docan>
to psindoc

And
<docverantwortlich>\xmltext{#1}{../../pverantwortlich}</docverantwortlich>
to psoutdoc

before writing the ps[in|out]doc to an extra file.

But thinking about it, it may be easier to load a <doclist></doclist> tree from a separate file
and add / edit the doc entries based on the <docnr>.
(<docnr>s are unique.)

This part isn’t even in my head now.

It did, thanks!
Right now the document does what I wanted to do in ConTeXt.
I’m tempted to write the remaining functions in lua instead of python.

Still a lot to learn ahead.

Greetings Axel
