I’'ve taken a look at the protocol docs of Openfire and saw that none of these protocols were implemented.
They ARE a valuable asset used by most jabber users.
XEP 0018 has been rejected
XEP 0186 is a draft
XEP 0126 is accepted b yXMPP standards group.
It’‘s quite easy to implement 0126 and we’'d like to see it in future Openfire releases.
Keep up the good work, devs.
