[xacml] [CR] Schema change of Defaults element

I propose to change the XPathVersion element and to add a new
"XPathNamespace" element as follows:

(1) Schema change request
<xs:element name="XPathVersion" type="xs:string" substitutionGroup
="xacml:AbstractDefaults"/>
==>
<xs:element name="XPathVersion" type="xs:anyURI" substitutionGroup
="xacml:AbstractDefaults"/>

(2) Schema addition request
<xs:element name="XPathNamespace" type="xacml:XPathNamespaceType"
substitutionGroup="xacml:AbstractDefaults"/>
<xs:complexType name="XPathNamespaceType">
  <xs:attribute name="NamespaceURI" type="xs:anyURI"/>
  <xs:attribute name="Prefix" type="xs:QName"/>
</xs:complexType>

(3) Text change request
In Section 5.3, Element <PolicySetDefaults>, line 1487-1489,

<AbstrractDefaults>[Any Number]

This is the head of substitution group to specify default parameters. The
elements in this substitution group defined at this time are <XPathVersion>
element and <XPathNamespace> element.
