Hi John,
That's a bug. Please file a report in bugzilla, attaching these
schema/instance documents.
If all you want to assert is really that "all guids must be unique", then
there is a workaround: replace your selector's xpath with .//*. This
produces the correct result on this file anyway.
Hope that helps,
Neil

Subject: problem with keys

Please respond to
xerces-j-user
I'm rather stuck here and am wondering if I'm trying to do something
invalid or what. This schema and instance document validate with xsv, but
not with Xerces (2.5.0). Attached are the instance and schema documents.
I'm
using the xerces sample dom.GetElementsByTagName with arguments -v -s. The
problem appears to be that xerces doesn't like it when the selector
of a key contains a parent element and it's child, like so: <xs:selector
xpath="./dome:Model|./dome:Model/dome:Entity"/>
Any help would be greatly appreciated.
