regarding all the unsigned byte talk: I agree with Charlie's point that the "old" way need to be retained for backward compatibility. but the text could use some clarifying. Maybe something like:
... Unsigned types should be used for unsigned data if possible. If the underlying file format dows not support unsigned types, byte, short, or int types can be treated as unsigned by using the NUG convention of indicating the unsigned range using the valid_min, valid_max, or valid_range attributes. ... -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [email protected]
