Section 6 says: 

EQUAL, HCOLON, SEMI, name-addr, addr-spec, and generic-param are
defined in RFC 3261 [2].

It should say:

EQUAL, HCOLON, SEMI, name-addr, addr-spec, and generic-param are
defined in RFC 3261 [2].

If the URI contains a comma, question mark or semicolon, the URI MUST
be enclosed in angle brackets (< and >).

Notes:

If addr-spec is used when there are parameters, it is ambiguous if the parameters are URI parameters or served-user-param. For consistency with RFC 3261 section 20, the same bracket rule is indicated even if comma and question mark do not cause an issue.

Section 6 says: 

   sessioncase-param        = "sescase" EQUAL "orig" / "term"
   registration-state-param = "regstate" EQUAL "unreg" / "reg"

It should say:

   sessioncase-param        = "sescase" EQUAL ( "orig" / "term" )
   registration-state-param = "regstate" EQUAL ( "unreg" / "reg" )

Notes:

The ABNF as written does not take into account that concatenation binds tighter than alternation.
