Hi all,
Can anyone tell me why we need parameter field in the content-type header?(I am using MMS v1.2). I have seen this for a multipart/related message. This parameter field is missing for some messages. This is my content field header.
84 13 B3 89 61 70 70 6C 69 63 61 74 69 6F 6E 2F 73 6D 69 6C 00

13 = length (19d)
B3 = application/vnd.wap.multipart.related
89 = Parameter Type
61 70 70 6C 69 63 61 74 69 6F 6E 2F 73 6D 69 6C 00 = application/smil.

I dont understand what is the significance of application/smil here.
Is it telling us the presentation part is of SMIL?

Can anyone give light on this?

thanks,
Dinu
