XML configuration files

[Harry]

Thanks Don and Tom. To be a bit more specific about my problem if we used
the data from NCEP GFS 80KM CONUS. I want to limit the possible options
available under Fields to geopotential at isobaric levels(IL), temperture at
IL, temperture at fixed heights, and a couple of other thing like humidity
if the data allows for it. However I can't just remove the extra data from
the set because I may need to show options for derived quantities like wind
speed while not showing options like u component or v component at a fixed
height above ground..
