Section 7.1. says:
<dm:deviceID>mac:8asd7d7d70</dm:deviceID> ... <dm:deviceID>mac:8asd7d7d70</dm:deviceID>
It should say:
Replace both with <dm:deviceID>urn:uuid:698137d0-b395-11e0-aff2-0800200c9a66</dm:deviceID>
As mentioned in Errata ID 2131 and 2962 a valid URN as defined in RFC3406: Uniform Resource Names (URN) Namespace Definition Mechanisms should be used for <dm:deviceID>. This is not the case for this example.
RFC 4479 in section 3.4. Device RECOMMENDS version 1 UUIDs for the <deviceID> element: "For devices with a MAC address, version 1 UUIDs are RECOMMENDED, as they result in a time-based identifier that makes use of the MAC address."
