revisit namespace URI changes for minor versions

1.3.7 Compatibility with JDF and prior versions of XJDF Backwards compatibility within versions that belong to a major release is a design goal for all CIP4 standards. XJDF was a major revision and therefore is aligned with JDF but is not backwards compatible with JDF. This specification - XJDF 2.1 is designed to be backwards compatible with XJDF 2.0. Therefore any valid XJDF 2.0 document will also be a valid XJDF 2.1 document. The namespace URI for XJDF remains the same as for XJDF 2.0: "http://www.CIP4.org/JDFSchema_2_0". The version of an XJDF or XJMF document SHOULD be specified in XJDF/@Version or XJMF/@Version. can be transformed into a valid XJDF 2.1 document simply by updating the namespace URI for the xjdf namespace from "http://www.CIP4.org/JDFSchema_2_0" to "http://www.CIP4.org/JDFSchema_2_1" . Table 3.1: XJDF Version ? New in XJDF 2.1 enumeration @Version SHALL define the version of the XJDF document. The value of @Version SHALL be "2.1" for documents that comply to this specification. A value of "2.0" MAY be specified for XJDF elements that comply with XJDF 2.0 in all aspects except for the presence of @Version. Table 7.1: XJMF Version ? New in XJDF 2.1 enumeration @Version SHALL define the version of the XJMF document. The value of @Version SHALL be "2.1" for documents that comply to this specification. A value of "2.0" MAY be specified for XJMF elements that comply with XJDF 2.0 in all aspects except for the presence of @Version.
