Hi,

Mhm, yes it's not kind of usage I've expected. I'll take care of
this bug. Can you please file this bug on bugzilla.ximian.com ?

Current codebase is based on old XmlSchema.Compile(), so it is
likely to happen that mono fails to compile it (and MS
implementation should be correct there).

Thanks,
Atsushi Eno
