hi:
I would like to ask you some questions about multimedia content encoding.
In the "8.5 Multipart Data" section of WAP-203-document , refer to the structure of MMS Body,but I still cann't find their specific coding.
for exmaple(How_to_create_MMS_services （http://www.forum.nokia.com/）):

"Message Body
The next byte (07h) indicates that the multipart message body in this example consists of seven parts.
Each of the parts follows the pattern of: <length of content-type + other possible headers>, <length of data>, <content-type + other possible headers>, <data>. We’ll look at the first part in detail, so you can get an idea of how this works.
The first part starts at position 0068, which is 23h, so the content-type + other possible headers will be 23h, or 35 bytes long. Next is 85h and 1Dh. These are a long integer. The most significant bits are not used, and the rest of the bits are concatenated to get the intended value 29Dh – this indicates the length of the data. The next 35 bytes should contain the content-type, and possibly other headers. The content-type is not one with a defined WSP encoding, so it is expressed as text, “application/smil”. At this point the 35 bytes has not been completely used, so there are more headers. The next header is in plain text: “Content-ID”, and its value is at position 0087: <0000>. The actual data extends from position 008E to position 032A (29Dh bytes total)."
1)The length is 85h and 1Dh.why the result length is 29Dh?what is the structure of length ?Is there same document describes the details of it?
2)In the How_to_create_MMS_services-document also Reference "B3h is application/vnd.wap.multipart.related, 89h is the type parameter, and its value follows as plain text – “application/smil”. 8Ah is the start parameter, and its value is <0000>".But at "http://www.wapforum.org/wina/wsp-content-type.htm" , not show "B3h is application/vnd.wap.multipart.related" .
Is there any other specifications referred to Assigned Number of other Content Type?
