Hi Christer,

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.  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.

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.
