  XInclude is parsing the included document first then include it.
So obviously it's b) , XInclude works at the infoset level, not as 
some parser magic, you generate the infoset with a normal parser.
  Anyway I suggest to not use a path for the public identifier.
  Use a canonical URL for your system identifier, use that canonical URL 
in the documents, and map it to the local resource in the catalog.

  Yes I think so, though I'm not sure I did much testing.

Reading the DocBook-Apps mailing list archive or googling for them
should have given answer to those, many people are doing the same
thing. Again wrong list, I don't understand why you insist getting this
on this channel, xsl-list is traffic intensive enough.
