Todd,
The answer to your xml:lang question. I will either incorporate it in
tonight's release or another alpha in the morning.

Please help!
I'm trying to use Xerces-J CVS (2.0 beta 3 beyond) version to
validate the xml:lang namespace, but got the following error:
[Error] test.xml:38:25: cvc-complex-type.3.2.2: Attrib
ute 'xml:lang' is not valid respect to the attribute wildcard of
Elment 'FreeText'.
Is my example incorrect or is something else? Can anyone help?
I'm enclosing the .xsd and .xml at the bottom.
Thanks!

<annotation>
<documentation>This schema defines attributes and an attribute
group
suitable for use by
schemas wishing to allow xml:lang or xml:space attributes
on elements they define.
To enable this, such a schema must first declare the XML
namespace, and then import this schema
for the XML namespace, e.g. as follows:
&lt;schema . . . xmlns:xml="<A HREF="http://www.w3.org/XML/1998/namespace"">http://www.w3.org/XML/1998/namespace"</A>;>
. . .
&lt;import namespace="<A HREF="http://www.w3.org/XML/1998/namespace"">http://www.w3.org/XML/1998/namespace"</A>;
schemaLocation="<A HREF="http://www.w3.org/XML/2000/10/xml.xsd"/">http://www.w3.org/XML/2000/10/xml.xsd"/</A>>
Subsequently, qualified reference to either of the attributes
or the group defined below will have the desired effect, e.g.
&lt;type . . .>
. . .
&lt;attributeGroup ref="xml:specialAttrs"/>
will define a type which will schema-validate a instance
element with both xml:space and xml:lang attribute</documentation>
