What about wildcards? I guess things should be OK as long as there is no 
wildcard in the XMPP OID (i.e., id-on-xmppAddr). But what should the 
receiving server do if the connection comes from "conference.jabber.org" 
but the id-on-xmppAddr has "jabber.org" (even if the dnsName has 
"*.jabber.org") and the OID is checked first?
