I was just discussing the possibility of doing without the XML of a
primary extension and documenting a simple convention instead:
> "If two resources have the same priority then subscribers
> SHOULD consider the primary resource to be the one that they
> last received a <presence/> stanza from."
> Another advantage of this approach (in addition to not
> requiring new <presence/> content) is that whenever the primary
> resource changes (to another resource with the same priority)
> the server only needs to send a single <presence/> stanza.
> (The current proposal requires two stanzas to be sent, one
> with and one without the <primary/> element.)
I was interested if anyone sees any reasons not to do it this way
