Summary: ready with minor issues



Major issues:



None



Minor issues:



1.       In order to accommodate the Websocket binding this document describes several deviations from RFC6120. For example, in Section 3.3 it says:

The WebSocket XMPP sub-protocol deviates from the standard method of

   constructing and using XML streams as defined in [RFC6120] by

   adopting the message framing provided by WebSocket to delineate the

   stream open and close headers, stanzas, and other top-level stream

   elements.

              I am wondering whether it would not be appropriate to reflect this in the document header by adding Updates RFC6120



2.       In Section 3.6.1:



   If the server wishes at any point to instruct the client to move to a

   different WebSocket endpoint (e.g. for load balancing purposes), the

   server MAY send a <close/> element and set the "see-other-uri"

   attribute to the URI of the new connection endpoint (which MAY be for

   a different transport method, such as BOSH (see [XEP-0124] and

   [XEP-0206]).



        I do not understand the usage of MAY in this paragraph. Is there another method to move to a different Web socket endpoint that is described here or some other place? In not, why is not the first MAY at least a SHOULD? The second usage seems to describe a state of facts, so it needs not be capitalized at all.





Nits/editorial comments:



In Section 3.1 I believe that the example should be preceded by some text that indicates that this is an example, such as: 'An example of a successful handshake and start of session follows:'
