Are you just meaning the binary mms file - or the binary mms notification? If you have a look for:
WAP-203-WSP-20000504-a.pdf WAP-209-MMSEncapsulation-20020105-a.pdf (There may be newer versions of them, I haven't checked) Also, a nokia document: How to Create MMS Services_v3_21.pdf ..has some nice pictures and a graphical explanation of things..

Basically, I can parse all of the headers and the body of the message, but I cannot find a reference which descibes exactly how a text MIME messages with a SMIL and multiple data bodyparts is encoded into the binary PDU. Specifically, I cannot find any reference to how the binary PDU indicates the end of the header fields, the number/content-type of bodyparts, etc. If anyone could point me to a useful discussion, worked example, or specification for this, I would be grateful.
