Attribute wildcard - processContents (XSV and MSXML bug)

Hi,

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..."
