If you're indexing in any way (walking a Blob or shredding) then you
need some form of schema support...

As I pointed out yesterday, there's more-or-less a direct mapping
between XML mixed content "annotations" and Aspect oriented
programming annotations.  Building a mixed content data structure
isn't the problem, at this point I don't see how to generally use
schema driven parsing to populate such a structure.  It would be
straight forward populating such a beast directly via a hard coded SAX
parser.  The issue is, can you automate the building of the parser
without some form of meta-meta description?  I can't see how, and
existing Schema languages don't appear to be up to the task.
