Perhaps you could comment on how the final assertion plays with the  
goal of publishing multiple application specific vocabularies (which  
I agree with strongly, particularly for VOEvent).

Will UCDs (and utypes, for that matter) simply become instances of  
vocabularies?

However, note that the VOEvent <Why> element relies on natural  
language.  There is no particular reason that SV and UCD might not be  
deemed "natural".
