Hi,

One small comment.

Section 6 says:

   "An MSD or a metadata/control block is always enclosed in a multipart
   (normally multipart/mixed) body part (even if it would otherwise be
   the only body part in the SIP message), since as of the date of this
   document, the use of Content-ID as a SIP header field is not defined
   (while it is defined for use as a MIME header field)."

draft-ietf-sipcore-content-id, which defines Content-ID as a SIP header field, has now been adopted by SIPCORE.

So, I wonder whether we could simply remove the second part of this paragraph? I don't think we need to change anything else, because I think we still want to always enclose the stuff in a multipart.

Regards,

Christer

Unless there are objections to this by Feb 15, we’ll move forward with the document approval.

Thanks,
Alissa

This was necessary because the designated expert for MIME content type structured content suffix pointed out that ASN.1 PER encoding can't be understood independently of the content (unlike XML, which can be parsed without understanding the content).  As a result, the MIME content type has changed from application/emergencyCallData.eCall.MSD+per to application/emergencyCallData.eCall.MSD.
