Re: [ebxml-cppa] CPP identification revisited

[Christopher Ferris <chris.ferris@sun.com>]

The problem with a UUID is that it gives no clue
as to what authority created it! Sure, the value space
is unique, but absent the context in which it was assigned,
one has little recourse to learn more about the artifact
to which the identifier was assigned.

IMO, what is needed beyond a UUID is a resolvable URI
that can be used absent any further context to dereference it.

Cheers,

Chris
