[emergency] RE: EDXL common distribution element

[Rex Brooks <rexb@starbourne.com>]

My $.02 FWIW:

I actually agree with Michael even though I have been doing my own 
diligent best to help move this effort forward as fast as it was 
originally asked of us to move it by EIC and the ad hoc EDXL group 
that first recognised the need. (Please overlook the "s" in place of 
and due to the lack of a lower case Z).

Over the last year and half I have been working on a recommendation 
for an informal standard for developing standards, even for diverse 
problem areas such as device and messaging independence.

It is similar to what Michael suggests, though different, but it 
starts with the kind of survey suggested, moves to developing 
real-world scenarios that follow well-known processes as far as they 
can be modeled, then builds UML Use-Cases for the range of known 
necessities, and from those models builds a formal Requirements 
Document, with a base UML model of the combined use-cases. From such 
a starting point any specification can then be checked against the 
Requirements to be certain that the actual requirements have been 
addressed. There are other features of this evolving recommendation 
which make this easier all around for both the standards-writers and 
the implementors, but I won't go into that particular song and dance 
(thanks be!).

Just my $.02.
