one of the things that can already be done ...

\def\xmltexdirective#1#2{\doif{#1}{command}{#2}}

\xmlinstalldirective{tex}{xmltexdirective}

         <?context-directive tex command \inframed{xxx} ?>
         <?context-directive tex command \page ?>

(the #2 is something without spaces btu one can work around that)

Aha. Useful, thanks!
