Michael,
Thanks. Based on this I forced the use of the correct impl by calling
DocumentBuilderImpl and also XMLSchemaFactory. And the problem did not go
away. So while there may be classloader issues that caused me to use the
wrong parser, the right parser also rejects this file, but only inside a
webapp.
In case it rings any bells, the validation error is:
cvc-complex-type.3.2.2: Attribute 'lang' is not allowed to appear in element
'regexp'.
The schema is so embarassingly simple that I'll include it here. I can't
figure out how it would ever reject a lang attribute on a 'regexp', let
alone only inside of the webapp.
<xs:schema targetNamespace="" elementFormDefault="unqualified"
xmlns:xs="http://www.w3.org/2001/XMLSchema";
attributeFormDefault="unqualified">
<xs:element name="regexpset">
<xs:complexType>
<xs:sequence>
<xs:element name="define" minOccurs='0'
maxOccurs="unbounded">
<xs:complexType>
<xs:simpleContent>
<xs:extension base="xs:string">
<xs:attribute name="name" use="required" />
<xs:attribute name="lang" use="optional" />
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>
<xs:element name="regexp" minOccurs='0'

</xs:complexType>

</xs:element>
</xs:schema>
