[stir] draft-ietf-stir-rfc4474bis-16: Syntax question

[Christer Holmberg <[e-mail]>]

Hi,

Section 4 says:

   "Note that unlike the prior specification
   in RFC4474, the Identity header field is now allowed to appear more
   than one time in a SIP request.  The revised grammar for the Identity
   header field builds on the ABNF [RFC5234] in RFC 3261 [RFC3261]
   Section 25.  It is as follows:

      Identity = "Identity" HCOLON signed-identity-digest SEMI
      ident-info *( SEMI ident-info-params )
      ..."

However, that syntax does NOT allow multiple Identity header fields, according to the rules in RFC 3261:

   "Multiple header field rows with the same field-name MAY be present in
   a message if and only if the entire field-value for that header field
   is defined as a comma-separated list"

It should be something like:

     Identity = "Identity" HCOLON signed-identity * (COMMA signed-identity)
     signed-identity = signed-identity-digest SEMI identi-info * (SEMI ident-info-params)
     ..."

Or, misunderstood I have?

Regards,

Christer
