Schemas is huge, hard, (obfuscated?) and ATM I'm focusing on Relax-NG instead
Concerning SAX, I dislike the interface, and suggest people use the new
reader interface. Doing the treaming validation in that environment should
be quite simpler since part of the tree based interfaces can probably be
reused as-is like I did for DTD validation and I expect to do for Relax-NG
in the future.

  The xmlschemas.c and xmlschemastypes.c sources are basically the
current (incomplete) implementation of XSD for the tree interface.
