inclusion of tex code in xml context

inclusion of tex code in xml context

[Meer, H. van der]

I have some difficulties understanding the intake of ConTeXt-code in an XML processing environment.
The setup is as follows.

\startbuffer[buffername]
\startuseMPgraphic{graphicname}{}
..
\stopuseMPgraphic
\stopbuffer

Processing inside xmlsetup:

\startxmlsetups xmlcommon:mpgraphic
  Here I want to read the buffer and then call it up with
  \useMPgraphic{graphicname}{}
\stopxmlsetups

This works if I pack the graphic definition in the buffer inside a <tex></tex> node and call
  \xmlprocessbuffer{tex}{\xmlatt{#1}{buffer}}{}
where <tex> is a ConTeXt processing setup.

This actuallty works, but has the drawback of putting the ConTeXt code inside <tex></tex> thereby makeing it difficult to reuse the definition of the graphic in a non XML-context. I thus want to get rid of the <tex></tex> enclosure.

I tried things like
  \xmlloadbuffer{tex}{\xmlatt{#1}{buffer}}
  \xmlsetup{tex}{xmlcommon:tex}    <== the tex processing xmlsetups
But this does not work. Because the graphic in this case is not found by \useMPgraphic.
Clearly I am misunderstanding some of the intricacies of the xmlloading macros and probably the solution is quite simple. But I cannot find the right way to do it.
Any help would be appreciated.

you can look for \xmlcontext and \xmlflushcontext
