Ok I have fixed the patch to accommodate "unmaskedvalue" and also
corrected a small error which applied the changes to some fields which
were not necessarily subfields. I am new to contributing code to open
source projects... Please guide me on how I can get this patch verified
and make it into the main build...

Subject: Re: [Ethereal-dev] Patch (PDML fields less than one byte)
Upon further reading of the PDML specification at:
http://analyzer.polito.it/30alpha/docs/dissectors/PDMLSpec.htm
I see that you're right, but if we're going to show bit values in hex in
the "value" attribute, then we need to also add the "unmaskedvalue"
attribute for those fields. The "unmaskedvalue" attribute will show the
hex value of the entire byte or bytes.
