Comment (by jonathan):

 Dear all

 I agree with Bryan, Karl and David. Helpful software may combine the
 contents of attributes, but as far as the data model is concerned, I have
 always understood the convention of "variable attribute takes precedence"
 to mean that the global att can be ignored if the variable has its own
 att. The global att is a default for all variables in the file and is
 therefore irrelevant when a default is not required. In Jon's terms, I
 think that means the att can be inherited and overridden but is not
 aggregated. Of course this is not true of most CF atts - only the ones
 which are permitted both as global and variable atts.

 Best wishes

 Jonathan
