It passes for me also in 2.6.32. However, the W3C schema validator only
complains when I check the option "check as complete schema", otherwise, it
passes without complaint. Still, libxml2 might be better off considering a
schema it parses a complete one.

Does it complain when you try to validate XML documents with this schema?
