I suppose that AFs could be used for that, but it doesn't really seem
necessary -- the second document can be parsed against its own DTD in
XML, just as SUBDOCs are in full SGML, and then the processor can
simply merge the two groves on output as specified by the XLL markup
in the master document.

Exactly.  As in SQL, it is a processing problem.

All the best,
