Comment (by ngalbraith):

 '' Is this syntax used only when an ancillary variable is associated with
 more than one data variable ''

 That would be difficult or impossible to enforce, since so many data files
 can be split up on the fly via thredds and other services.

 Also, we might want to consider allowing all 4 of the existing modifiers
 to have standard names (or category names, as was suggested earlier), as
 long as they are applied to primary data variables that share units. There
 could easily be a single detection_minimum, and maybe also a single
 standard_error, for e.g. wind or current vectors.
