v1.0 and vocabularies

If I understood xml better, I guess I would know the answer to this 
question, but here goes.

Suppose I had a variable list, e.g. (taken from the documentation page)

<variables xmlns="http://www.unidata.ucar.edu/namespaces/thredds/InvCatalog/v1.0"; 
>
 <variable name="wv" vocabulary_name="Wind Speed" units="m/s"/>
 <variable name="wdir" vocabulary_name="Wind Direction" units= "degrees"/>
 <variable name="o3c" vocabulary_name="Ozone Concentration" units="g/g"/>
 ...
</variables>



Suppose I want to say that the units are udunits compliant.  Can I write

<variables xmlns="http://www.unidata.ucar.edu/namespaces/thredds/InvCatalog/v1.0"; 
>
<variable name="wv" vocabulary_name="Wind Speed">
  <units vocabulary="udunits>m/s</units></variable>
 <variable name="wdir" vocabulary_name="Wind Direction">
   <units vocabulary="udunits>degrees</units></variable>
 <variable name="o3c" vocabulary_name="Ozone Concentration">
  <units vocabulary="udunits">g/g</units></variable>
 ...
</variables>

I certainly would like to be able to do so.
