Hi Frank, how is this? (BTW I also changed the order slightly.)

###

4.  Recommendations for Protocol Designers

   Designers of new application protocols that allow extensions using
   parameters:

   1.  SHOULD establish registries with potentially unlimited value-
       spaces, if appropriate including both permanent and provisional
       registries.

   2.  SHOULD define simple, clear registration procedures.

   3.  SHOULD mandate registration of all non-private parameters,
       independent of the form of the parameter names.

   4.  SHOULD identify a convention to allow local or implementation-
       specific extensions, and reserve delimeters for such uses as
       needed.

   5.  SHOULD NOT prohibit parameters with the "X-" prefix from being
       registered with the IANA.

   6.  MUST NOT assume that a parameter with an "X-" prefix is non-
       standard.

   7.  MUST NOT assume that a parameter without an "X-" prefix is
       standard.
