Section 9.2 says:
A P-Preferred-Identity header field value MUST consist of exactly one name-addr or addr-spec.
It should say:
A P-Preferred-Identity header field value MUST consist of exactly one name-addr or addr-spec. If the URI contains a comma, the URI MUST be enclosed in angle brackets (< and >).
While the P-Asserted-Identity and P-Preferred-Identity header fields have an ambiguity only for "," (not for ";" and "?"), we note that usage of ";" and "?" also must be enclosed in angle brackets to preserve consistency with the RFC 3261 section 20 bracket rule.
