Hi,

STOX Presence specification was published as RFC already back in May 2014 (https://datatracker.ietf.org/doc/rfc7248/). Only a few days later it was discovered it has errors on how the message flows were drawn. Basically, in 7248 message flows, SIP-to-XMPP gateway takes care of all messages oriented from the SIP side, while a logically separate XMPP-to-SIP GW takes care of all messages oriented from the XMPP side. The problem in those flows is that even individual transactions are split across two GWs in this manner: the response is handled by a different GW than the request. This would cause problems to state maintenance in the GWs. See more details in http://www.ietf.org/mail-archive/web/stox/current/msg00507.html. 

This could be fixed by issuing an errata, but fixing message flow diagrams in an errata is not the cleanest approach. So, Peter has submitted an entirely new (bis) version of the document (https://datatracker.ietf.org/doc/draft-saintandre-stox-7248bis/), which when published as RFC would obsolete 7248. In practice the difference between 7248bis and 7248 is merely an editorial correction.

STOX co-chairs are proposing that the best way forward indeed is the publication of 7248bis as an RFC. This is to our understanding the preference of the RAI ADs too. As this should be a relatively simple (editorial) matter, the chairs are proposing the following:

1.) draft-saintandre-stox-7248bis is adopted as STOX WG document.
2.) A WGLC is initiated on the WG document as soon as it is available.

If someone has issues why this should not be done or has questions or comments, please post them on the STOX mailing list within a week, i.e. latest on March 3. If there are no issues, the chairs will start the WGLC on March 4. (On the WGLC we want a couple of reviews to make sure there are no bugs left this time :-)
