Notes
-----
The identity element is defined as maxOccurs="1" in the XML schema. However, in the section 4.1.6 of RFC4235, it says "Note that multiple identities (for example a sip: URI and a tel: URI) could be included if they all correspond to the participant". This seems to contradict with the XML schema.
