We might want to allow multiple variable vocabulary names to each

For instance,

<vocabulary_name vocabulary="CF-1.0">Wind Speed</vocabulary_name>
<vocabulary_name vocabulary="DIF">EARTH SCIENCE, Atmosphere,
Atmospheric Winds, Surface Winds</vocabulary_name>
<units vocabulary="udunits>m/s</units>
</variable>

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>
That's right. As InvCatalog 1.0 stands, the variables element is only
allowed once per dataset element and once per metadata element, so
repeating the variable information for different vocabularies would
require enclosing each in a seperate metadata element.
