[jdev] XEP-0153 Avatars conflict with several resources

[Alban Crequy]

Hi,

If a Jabber client sends this kind of <presence> stanza with an empty
update node as per XEP-0153 (avatar) section 4.4, 1st bullet:

<presence id="1900"> <x xmlns="vcard-temp:x:update"></x>
 <c ...></c> </presence>

Is the Jabber server allowed to modify the content of the presence
stanza by add a <photo> node before broadcasting it to contacts and
other connections on the same account but different resources?

Would it be a bug in the Jabber server?

Regards,
Alban
