Re: Full Feature Phase and Digests

Randy,

First off, there was a typo in my earlier email -

" LOGGED_IN marks the beginning of the full-feature phase, IN_LOGOUT
  and LOGOUT_REQUESTED (states S6 and S8) .."

I should have typed "S7" instead of "S8" - sorry.

Thanks for pointing out 5.1.2!  I will remove the paranthesized text,
and add the above clarification instead to the text.

You aren't nit-picking - these are the questions we asked earlier ourselves.
I believe the first para on page 37 answers your questions - FFP ends 
right after Logout Response (sent/received based on the role) if Logout did
take place, or else on transport connection removal.

Thanks!
