short names (descriptors) proposal

["Kurt D. Zeilenga" <Kurt@OpenLDAP.org>]

A number of interoperability problems have been raised regarding
the use of non-unique short names.

I suggest replacing the existing [Models, Section 6.2] text with:

  Short names (descriptors) used to identify various schema elements
  SHOULD be registered unless in private-use name space (e.g.,
  "x-").  Names used to identify elements defined in RFCs MUST be
  registered.

  Procedures for registering short names are detailed in BCP 64
  [RFC3383].

With this change, I believe it reasonable to then update
the DN string specification to support use of any properly
registered name.

Comments?
