Throughout the document, when it says:
It should say:
Throughout RFC4596, msgserver is used as a feature tag while its use was never standardized. A standards compliant proxy server would simply ignore this msgserver parameter. msgserver was used in some UA capabilities draft but was later changed to actor="msg-taker".

See http://www1.ietf.org/mail-archive/web/sip/current/msg08884.html for when the change took place.
