Jon,

As the working group archives over the last couple of years will show,
2778/2779 "requirements" were consistently cited as the reason one or
another feature had to be included in CPIM.

Therefore, failure to satisfy those requirements raises a very real
specifications. When 2778/2779 was cited, there were no discussions
about satisfying requirements selectively. Had there been, there would
have been a question about the basis for choosing which requirements to
satisfy.

By way of confirming the original this original intent for CPIM, note
early text from a CPIM draft: "The CPIM profile meets the requirements
specified in RFC 2779 using a minimalist approach allowing
interoperation of a wide range of IM and Presence systems."

Any change in this goal happened long after the work of The Nine.

The key phrase in the specifications is "common semantics and data
formats".  That is rather more than just "a set of tools".

a specification that provides detailed, end-to-end syntax and semantics
is rather more than "an abstract model".

Given that satisfaction of 2779 was constantly cited as a requirement
during the working group's efforts, then having the charter call for
satisfying those requirements would be merely be an accurate recording
of how the working group actually chose to behave.
