This thread is for discussing draft-cdh-mpls-tp-psc-non-revertive-00.  This draft adds a MS-W (Manual Switch to Working) command and modifies the PSC text and state machine to handle this new command.  The proposed MS-W command is of equal priority to the existing MS-P command, and there is text to handle the simultaneous or sequential occurrence of two equal-priority commands.

Relevant questions include:

- do we need MS-W and the associated state changes?
- PSC currently does not have any commands with equal priority.  Should we employ such a mechanism to address either this issue or future additions to PSC?
- if so, is the method proposed in the draft the correct one?
- if not, do we need any additional mechanism to handle the issue this draft raises?

 but of course any and all discussion is welcome.
