Defines that this AliasIdentification represents a "Universally Unique Identifier". Although a UUID is technical definition of a 128-Bit number, the primary relevance of this type is not its technical representation, but it’s other properties. An AliasIdentification with the type "UUID" of an element is its unique identifier, that is constant over time, never changes and is never reused for other elements. Such an AliasIdentification can be used to trace elements through different systems, companies and processes.
