xsd:element attributes with non-schema namespace

I have a question about attributes with a non-schema namespace in an
xsd:element definition.  For example, I want to add an attribute "my:attr"
in the following way:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"
xmlns:my="http://my.name.space">
	<xsd:element name="test" my:attr="something"/>
</xsd:schema>

Seems the CR XML Schema does not allow this, at least according to a
couple of tools that I have tried using to validate the schema:

"This file is not valid: Unexpected attribute 'my:attr' in element 'xsd:element'"

I believe this should be allowable, according to the XML Schema spec.
 Note the
"{any attributes with non-schema namespace . . .}" below:

<element 
  abstract = boolean : false
  block = (#all | List of (extension | restriction | substitution)) 
  default = string 
  final = (#all | List of (extension | restriction)) 
  fixed = string 
  form = (qualified | unqualified)
  id = ID 
  maxOccurs = (nonNegativeInteger | unbounded)  : 1
  minOccurs = nonNegativeInteger : 1
  name = NCName 
  nillable = boolean : false
  ref = QName 
  substitutionGroup = QName 
  type = QName 
  {any attributes with non-schema namespace . . .}>
  Content: (annotation?, ((simpleType | complexType)?, (unique | key
| keyref)*))
</element>

Then I looked at the relevant XML schema definition in XMLSchema.xml
off of the w3c website:

	<xs:complexType name="element" abstract="true">
		<xs:annotation>
			<xs:documentation>
   The element element can be used either
   at the top level to define an element-type binding globally,
   or within a content model to either reference a globally-defined
   element or type or declare an element-type binding locally.
   The ref form is not allowed at the top level.</xs:documentation>
		</xs:annotation>
		<xs:complexContent>
			<xs:extension base="xs:annotated">
				<xs:sequence>
					<xs:choice minOccurs="0">
						<xs:element name="simpleType"
type="xs:localSimpleType"/>
						<xs:element name="complexType"
type="xs:localComplexType"/>
					</xs:choice>
					<xs:group ref="xs:identityConstraint"
minOccurs="0" maxOccurs="unbounded"/>
				</xs:sequence>
				<xs:attributeGroup ref="xs:defRef"/>
				<xs:attribute name="type" type="xs:QName"/>
				<xs:attribute name="substitutionGroup"
type="xs:QName"/>
				<xs:attributeGroup ref="xs:occurs"/>
				<xs:attribute name="default" type="xs:string"/>
				<xs:attribute name="fixed" type="xs:string"/>
				<xs:attribute name="nillable" type="xs:boolean"
use="optional" default="false"/>
				<xs:attribute name="abstract" type="xs:boolean"
use="optional" default="false"/>
				<xs:attribute name="final" type="xs:derivationSet"/>
				<xs:attribute name="block" type="xs:blockSet"/>
				<xs:attribute name="form" type="xs:formChoice"/>
			</xs:extension>
		</xs:complexContent>
	</xs:complexType>

It doesn't look like it allows for any attribute in a non-schema namespace.

This has worked prior to CR.  Should this be allowed or not?

Thanks,
