This is the well-proven design of a DCE UUID (officially, that is what it
is called).
No regard for human readability. The Universe is the context by definition.

If we go this route I would strongly argue we need BOTH.  The internal GUID
that is DCE based, and then the external UID that is the faciliator for
XPointer
and other human orientated access paths.

However - the question is - if we make a formal mechanism for the UID,
then the GUID is optional - except in a A2A context - but since most 
Registry interactions are predicated by a human interface this really
mean the UID is the preferred access path for most people.
