Hi there. I've been given a pretty large schema, distributed among a large
number of files. No validation errors are reported on the file that
represents the "root" of the schema. However, when I try to create a new
EMF project from that schema, I get the stack trace shown below.
After taking a look at XSDECoreBuilder under the debugger, it looks as if
the failure is occurring on an attribute that is or extends a type
("lang","space") from the xml namespace
(http://www.w3.org/XML/1998/namespace).
Given the size of what I'm looking at, it's been hard to narrow it down
much more. I'm wondering if anyone's seen something like this before, any
hint would be good. Or, maybe someone on the xsd development team could
have a look at the xsd files i'm working with... Thanks!
P.S. i'm using the 2.0.0 versions of both emf & xsd. and yes, the library
example works fine for me, and i'm using an ibm jre :-)

Thanks Ed. I've opened a bug with a more-digestible sample than my
original: https://bugs.eclipse.org/bugs/show_bug.cgi?id=71116

Hi,
If you make your schemas available, I'll try them out and fix any
problem I can reproduce. If the schemas are confidential, you can send
them to me directly, rather than posting them in public.
