Yep, I have this now:

    The syntax of the <message/>
    stanza, including required and optional elements and attributes, is
    defined in [RFC6121] (for single instant messages, Section 5.1 of
    [RFC6121] recommends that the value of the 'to' address be a "bare
    JID" of the form "localpart@domainpart").
