...although, if a UUID corresponds to a particular protocol, no matter
what version - just as the program number in ONC RPC corresponds to a
particular protocol, no matter what version - we could split the DCE
registration functions into a "dcerpc_init_uuid()" that takes a protocol
number, and ett value, and a UUID, and registered the UUID for that
protocol, and another routine that takes a UUID, a version number, and a
"dcerpc_sub_dissector *" and registers the dissectors for that version
of the protocol.  (I don't know which one would take the "opnum_hf"
argument; if different versions of the protocol can have different names
for particular operation numbers, it'd be the second routine, along the
lines of what's one for ONC RPC, otherwise it'd be the first routine.)
