support for ?

[Rebekah Lepro <rs...@psu.edu>]

I've been trying to get validation to fail after violating the unique 
requirement in a schema, and it doesn't seem to fail no matter what I 
do.  I took the example from the Schema primer too, and it fails.  I see 
that support is still experimental.  Is this not yet supported or am I 
doing something wrong?  I've included the schema and the document that I 
thought would fail validation because of the duplication within the code 
attribute of zip.  But it passes just fine?
Thanks,
Rebekah
