Certain people appear to want the entire UHF channel plan encoded in the PAWS 
response, using very low PSD values to represent permitted leakage into 
"unavailable channels".

IMHO, this is a very US/FCC-centric model.

In the ETSI model, each available channel is _explicitly_ listed, with a low 
and high frequency.  "Unavailable channels" are omitted, and there's no concept 
of needing to describe the channel plan.  Devices just do what they're told, 
and adjacent channel leakage into otherwise unusable channels is controlled by 
device approval regulations.

Option #2 _could_ be used to represent the ETSI model, but doing so changes the 
semantics from representing the channel plan to being a workaround to get 
around the inability of option #2 to explicitly specify "unavailable channels" 
without resorting to magic values.

So far we have few people speaking for either of the options.
We need to agree on this asap and move forward, so please send a mail to the 
list and indicate whether you are ok with either option, or you feel strongly 
for one or the other.

Strongly for #1, of course :)

I would also be happy with a variant of #1 where the profile is still presented 
as a list-of-lists to support representing a US-style non-contiguous channel 
plan, but which still permits frequency ranges to be omitted within each 
contiguous band).
