UDDI uses UUIDs and those UUIDs are specific to some particular

Absolutely true for UDDI V2, in which key values were expressed using a
URI format that starts with the characters "uuid:" followed by a
formatted UUID.  In UDDI V3, keys are of datatype anyURI. V3 also
supports publisher-assigned keys, in which a publisher is permitted to
propose a new key for an entity, and - given the policies of the
registry - that key and the entity associated with that key may be
inserted into the registry.
