[regrep] Support for "urn" attribute in RegistryEntry

[Len Gallagher <LGallagher@nist.gov>]

Regisrty TC,

Referenced below is a discussion paper I sent some time ago to the "query" 
team as we were discussing how to use the "id" attribute of RegistryEntry 
and other ebRIM classes.

    http://lists.oasis-open.org/archives/regrep-query/200109/msg00062.html

It is the outline of a proposal to add a new "urn" attribute to the ebRIM 
RegistryEntry class. I don't care if the attribute name is "urn" or 
something else, but I think it is very important that we have a 
globally-unique, human-friendly way to reference the "repository item" that 
is described by a RegistryEntry instance.

I'm referencing it again here to ensure that it gets on the Agenda for our 
upcoming F2F meeting, Oct 31 - Nov 2.

-- Len
