The discussions of Thomas's umbrella variable have touched on this point but it doesn't seem to suit the purpose of providing a single quality flag variable for an arbitrary selection of geophysical quantities. Hence I think the idea of generalising the standard_name att to the format standard_name [standard_name ...] modifier i.e. permitting more than two words in it would be more suitable and general-purpose. The main motivation for the umbrella variable is different viz. to identify a group of data variables which together constitute a single higher-level geophysical quantity.
