Ok, I wasn't suggesting that the URLs all had to be of one type -
the template I based the example on actually has provision for
multiple instances of the object, so you could say that all the
URIs belonged to the first instance, and we end up with something
more like this...

/ 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?

It's exactly what I had in mind!  At last - UR Consensus!! :-)
