A profile is really just a specification of the rules for how the protocols
shall be used to accomplish a certain usage scenario. Profiles do not contain
packet structure formats (except AVRCP, but that was a mistake). In some cases
like GAVDP, A2DP, VDP and AVDTP, the profiles/protocols are so closely
connected that they would never be used seperately.
I think it has been common practise in the Wireshark development to have
closely related dissectors in the same dissector file, see e.g. packet-ppp.c.
Anyway, I just wanted to give you my reasons for putting the profile dissectors
together with the protocol dissector.
