I'm by no means opposed to Joseph Reagle's proposal or the
formation of a new WS or SOAP security WG, which happens to
be in line with what Dave Orchard and some others were pushing
and receiving pushback.  (I as the sec champion would rather
be as neutral as possible on the issue, and stick with
shepherding the process with technical analysis and clarification
where appropriate.)  There were some concrete steps we were
slated to take in this area as an upshot of the Paris F2F.
For now I'd rather not jump the gun here before Chris the
chair's cue on the matter.

My messages were quite clear and simple, I think: 1) a rebuttal
to Dave Orchard's "observations" and mis-characterization of
the hitherto efforts and accomplishments in the security front
within WSAWG; and 2) a word of caution to arrest a potential
slide into finger pointing.
