\xmlcontext inoperative?

\xmlcontext inoperative?

[Meer, H. van der]

[-- Attachment #1.1: Type: text/plain, Size: 926 bytes --]

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?

By accident I found something that seems to work.
With \xmlregistereddocumentsetups{#1}{#1} put before the \xmlflush{#1} ConTeXt processing resumes on the node.
What I do not understand however, is why \xmlcontext does not work in general.
Is it possible to have the \xmlregistereddocumentsetups action put in somewhere or in such a way that \xmlflush and friends always succeed? I did not understand enough of the code to fully grasp what is is is not happening.

there is (if i remember right) an issue with the root node of an include 
that I need to look into (but not now as I need to be careful with 
compatibility)
