According to XEP-030 :
Each <identity/> element MUST possess the 'category' and 'type' attributes specifying the category and type for the entity
I don't actually understand what does the type attribute stands for.
For example, when I send a disco#info query to my MUC component, I get the following answer:
<iq to='admin@localhost/986758107-tigase-8' from='muc.localhost' type='result'>
<query xmlns='http://jabber.org/protocol/disco#info'>
<identity category='conference' name='Multi User Chat' type='text'/>
<feature var='jabber:iq:version'/>
<feature var='urn:xmpp:ping'/>
<feature var='http://jabber.org/protocol/commands'/>
<feature var='http://jabber.org/protocol/muc'/>
</query>
</iq>
the type is set to "text" but what does it mean ? is there any other purpose than just creating a unique combination with name and category ? Or maybe something else ?
Existing (category, type) tuples are documented here: https://xmpp.org/registrar/disco-categories.html. Conference+text is a "Text conferencing service", in other words a group chat server.
