Re: draft-ietf-sip-199-06

Hi,

Thanks for the text, Tom!

Regarding documenting that all 3 conditions must be fullfilled, and way
is to write ";and" after each condition.

 "When a forking proxy receives a non-2xx final response that it
  recognizes as terminating one or more early dialogs, it SHOULD
generate
  and send a 199 response upstream for each such early dialog satisfying
the
  following conditions:
  -- the proxy does not intend to forward the final response immediately
     (in accordance with rules for a forking proxy);and
  -- the UAC has indicated support for the 199 response code;and
  -- the proxy has not already received and forwarded a 199 response for
     that early dialogue."

Reegards,

Christer

[JRE] Make it clear that all 3 conditions must be true, e.g., by saying
"satisfying all of the following conditions".
