Does it serve any useful purpose, in reviewing the proposed "mid
and cid URL schemes" to point out that the RFC 822 MIDs and RFC
1521 CIDs are our leading legacy example of World-unique resource
_names_?  That is to say, creating a syntactic scheme whereby
they fit into the URI family is to create a class of URNs.  These
items are more aptly called URNs than URLs.  The information in
the URI does not tell you where to find the object or how to get
it.  They are identifiers by which we validate that we have an
instance of a particular named thing, given that we got a
candidate instance somehow.
