Correct the multiplicity of subscriptionReference in notification XSD
In TS-0004, multiplicity for subscriptionReference is 1 while in CDT-notification-v3_9_0.xsd XSD it's mentioned as optional. <xs:element name="subscriptionReference" type="xs:anyURI" minOccurs="0"/>
It should be corrected in CDT-notification-v3_9_0.xsd as below: <xs:element name="subscriptionReference" type="xs:anyURI"/>
