11、ights reserved iiiForeword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standa
12、rds through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and I
13、EC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is
14、 to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possi
15、bility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

Here, the 01 represents a serial number that is expected to change as this
19、 extension evolves. 10.4.3 Namespace prefixes For convenience, this extension uses shorthand namespace prefixes when referring to XML elements and types.

22、esults in certain rights being associated with the adapted resource. The optional attribute m1x:governanceRule of type QName indicates the name of a governance rule that determines how exactly the adaptation should be made and what rights should be associated and by whom. When the attribute is not s
23、pecified, this right allows adaptation of the resource and results in identical adaptation of the r:license such that related grant in the license are associated with the adapted resource.
