Attribute wildcard - processContents (XSV and MSXML bug)

Hi,

Due to a funky new security mechanism of the W3C mailing list,
my last message did not reach the list.
I got:
"...Your message has NOT been distributed to the list; before we
distribute it, we need your permission to include your message
in our Web archive of all messages distributed to this list..."

After following the process to permit everything needed, I
read that the message will be transmitted, but I don't see
it transmitted, so I try to repost it. Sorry if the original
message pops up from somewhere in the undefined future.

Potential bug in XSV and MSXML related to builing the
processContents of complete attribute wildcards.

<xs:schema
	xmlns:xs="http://www.w3.org/2001/XMLSchema">
	<xs:attributeGroup name="attrGroup">
		<xs:anyAttribute namespace="##any"/>
	</xs:attributeGroup>
	<xs:element name="foo">
		<xs:complexType>
			<xs:attributeGroup ref="attrGroup"/>	
			<xs:anyAttribute namespace="##any" processContents="lax"/>	
		</xs:complexType>
	</xs:element>
</xs:schema>

<foo 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:noNamespaceSchemaLocation="attr-wild.xsd"
	xmlns:b="urn:test:bar"
	b:bar="BAR"
/>

XSV 2.10 and MSXML 4.0 are not happy with this scenario, while
Xerces-J 2.7.1 is. XSV and MSXML become happy if and only if _both_
attribute wildcards are set to a processContents of "lax".

I think only Xerces is working correct here.

In [1] we have:

"2.2.1 If there is an <anyAttribute> present, then a wildcard whose
{process contents} and {annotation} are those of the ·local wildcard·,
and whose {namespace constraint} is..."
