It is possible to create a version of UUID that has information encoded in it - timestamp and the network node address. For some environments, such encoded information is not acceptable.

It is also possible to create a version of UUID that has no information encoded it it - it is truly a random identifier. In the mentioned environments, this is the only acceptable version of UUID. I defined a simpleType that constrains the set of UUIDs to only this version.
