Hmm....This is similiar to what Mitra was saying. But I think I'm warming
to the suggestion.

I would make some slight changes because what you are saying is that ALL
of those URLs are of type text. What do I do if I have a URN that is in
multiple formats? Add something like precedence and I think we might
have something. What I mean by precedence is that if a non-URI template
item appears after a URI: URN then that info is global. If it appears
after a URI: URL then it is only local to that specific example. Hmm...
do a %s/precedence/scope/ in the last paragraph. Basically you would
have:

Description:
The purpose of this memo is to initiate a discussion for a migration
path of the WAIS technology from Z39.50-1988 (Information Retrieval
Service Definitions and Protocol Specification for Library Applications)
to Z39.50-1992 and then to Z39.50-1994. The purpose of this memo is
not to provide a detailed implementation specification, but rather to
describe the high-level design goals and functional assumptions made
in the WAIS implementation of Z39.50-1988. WAIS use of Z39.50-1992
and Z39.50-1994 standards will be the subject of future RFCs.

Is this change unpalatable?
