  We state on the main page of the web site:

  http://xmlsoft.org/

"A partial implementation of XML Schemas Part 1: Structure is being worked
 on but it would be far too early to make any conformance statement about
 it at the moment."

  i.e. use at your own risk, it's not finished yet.

  Looks like a bug, it is deterministic...
Can you fill up a bugzilla report, with a complete schemas instance showing
the problem, thanks !

  There is no support for lax or partial XSD Schemas validation yet in libxml2
so it's not surprizing this raised an error.
