Sorry that I missed your previous commentary here, on the technical 
aspects of the draft that create a problem.
(Something must be misbehaving with either my mail system or the IETF's, 
since this is at least the second time I've seen a note from you 
offering a conclusion where I missed the foundation.)
Please point to the messages that have outlined what the details are 
that make it impossible for this draft to be viable.

Your certitude is impressive.  Please document its basis.

Given your extensive IETF experience, it's surprising that you'd offer 
an historical summary this skewed, covering some of what has been done, 
while missing so much else of what has been done.  In other words, it 
used to be done, sometimes.  And it still is.  Sometimes.  And it wasn't 
done, sometimes.  And it still isn't.  Sometimes.
