PolicyIdentifierListType definition in wd-15 xsd

["Tyson, Paul H" <PTyson@bellhelicopter.textron.com>]

Couldn't this:

	<xs:complexType name="PolicyIdentifierListType">
		<xs:sequence minOccurs="0" maxOccurs="unbounded">
			<xs:choice>
				<xs:element
ref="xacml:PolicyIdReference"/>
				<xs:element
ref="xacml:PolicySetIdReference"/>
			</xs:choice>
		</xs:sequence>
	</xs:complexType>

be simplified to:

	<xs:complexType name="PolicyIdentifierListType">
		<xs:choice minOccurs="0" maxOccurs="unbounded">
			<xs:element ref="xacml:PolicyIdReference"/>
			<xs:element ref="xacml:PolicySetIdReference"/>
		</xs:choice>
	</xs:complexType>

?
