Yes, you can certainly do this. I often do.

If I want to do it without disturbing the schema for the document, and 
without inventing private microsyntax, I use processing instructions:

<?glossary?>

as an instruction to the XSLT processor to insert the glossary at this 
point.

Usually (as in this example) the expansion is not literal text, but 
something generated by an earlier step in the processing pipeline.
