This nicely raises a fundamental question about how the WG plans on  
approaching the selection of SV tokens (assuming that there is a  
general acceptance of the idea of SOME vocabulary), something that  
has already appeared slightly different forms in the list: do we  
simply want a list of  all possible interesting words, assuming that  
the VO clients and apps will simply choose whatever word is  
appropriate, or do we want to define a vocabular basis of words which  
users and apps are expected to stick together in some hopefully  
simple fashion.

Example: do we want to propagate "sunspot" or do we what to propagate  
"starpot" and expect that the solar types will - somehow - be able to  
add on some more information that the "starspot" is on the Sun?   
Nowday, it's amazing how much of early solar terminology is being  
applied to other stars, so we don't need two or more names for the  
same thing.  This may not be the best example, but one which  
immediately popped into my head when the Sun was mentioned.

Our original proposal tried to keep the total number of tokens as  
small as possible by encouraging some form of concatenation (whether  
trivial ucd-like or fancy OWL-like), a goal I'd like to see kept in  
the forefront.
