service discovery - What is the "type" attribute in XMPP disco#info result -


according xep-030 :

each <identity/> element must possess 'category' , 'type' attributes specifying category , type entity

i don't understand type attribute stands for.

for example, when send disco#info query muc component, 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 set "text" mean ? there other purpose creating unique combination name , category ? or maybe else ?

existing (category, type) tuples documented here: https://xmpp.org/registrar/disco-categories.html. conference+text "text conferencing service", in other words group chat server.
