Thanks, Ron, I am greatly encouraged. My own take would be that Miss Katie cannot in any conscience agree to this (even though I think she at least implicitly signed it) and that they will carry on leaving the Communion. Now, if the Communion can then lock the doctrinal door on this and on female ordination, AND allow the use of the 1928 BCP and doctrine, then we are in a position to resume communion with them.
Oh, she signed it. And the Susan Russell's of TEC are hopping mad. They're talking about either TEC tells the AC to stuff it or they quit TEC.
