Hi Randall, >In rereading RFC 6086 and RFC 5621, I don't see any clear statement that the Content-Disposition of a top-level multipart within an INFO request should be Info-Package. Section 4.3.1 says: "If an INFO request associated with an Info Package contains a message body part, the body part is identified by a Content-Disposition header field "Info-Package" value. The body part can contain a single MIME type, or it can be a multipart [RFC5621] that contains other body parts associated with the Info Package." >RFC 6086 says Content-Disposition is optional at the top level of a SIP message, and the examples in RFC >6086 sometimes show no Content-Disposition at the top level. Upon careful rereading, my interpretation is that the innermost multipart that contains only body parts >associated with the INFO package perhaps should have a Content-Disposition of Info-Package. If there is only one multipart, then the innermost is also the top level. Correct. It's the innermost multipart that contains body parts associated with the INFO package that shall have a Content-Disposition:info-package. And, in the example of draft-ecall, that "innermost multipart" is the only multipart, so there shall be a SIP level C-D: info-package header field. >Therefore, I propose to add the following text: > > The innermost multipart that contains only body parts associated with > the INFO package SHOULD have a Content-Disposition value of Info- > Package (if there is only one multipart, then the innermost is also > the top level). > > And add the C-D header to the examples. I think it shall be "MUST", because I can't find any text making it optional.
