I have now checked in a change so that RTSE uses the packet-ber EXTERNAL
decoding.
(http://anonsvn.wireshark.org/viewvc/viewvc.py?view=rev&revision=23450)

Tomas: I had to make some minor changes to packet-ber.c to make things work
could you check?
	And if you could check packet-rtse.c to see if I have taken the
right approach - that would be great.

Anders: Is someone looking at doing something similar for ACSE (which still
uses an EXTERNALt)?

Stig: Can you check I haven't broken your x411 captures?

I think your patch is correct - but should adopt Tomas suggestions:
a) use the "*_ref_present" members; and 
b) try to do a presentation context lookup if an indirect reference is
found.
