An excellent point, which changes the way I think of attributes, and 
will probably change the way I code them:   any attribute controlled by 
vocabularies might have different values for different vocabularies, and 
thus might get repeated.  

I take it that if I am willing to repeat everything, I am supposed to 
create a series of metadata containers, each with a different 
vocabulary, e.g.

<metadata vocabulary="DIF" inherit=true>
<vocabulary_name>EARTH SCIENCE, Atmosphere, Atmospheric Winds, Surface 
Winds</vocabulary_name>
</metadata>
<metadata vocabulary="CF-1.0" inherit=true>
<vocabulary_name>Wind Speed</vocabulary_name>
</metadata>
