missing data and scale/offset standard attributes

The users guide is vague on the interaction between missing data and 
scale/offset standard attributes. Id like to propose adding the following:

1. The _FillValue and missing_value standard attribute values must be in the 
units of the packed data.

2. The valid_range, valid_max and valid_min standard attribute values should be 
in the units of the packed data.

3. To accomodate historical uses, if the valid_range, valid_max or valid_min values are 
wider than the packed data type, then these will be interpreted as being in the units of 
the unpacked data. Wider means: (byte < short < int < float < double ). 
Otherwise, they will be interpreted as being in the units of the packed data.


Comments solicited.
