This is partly an encoding issue; multiple values may be rendered in a 
different way depending on the format.  What is not an encoding issue is 
indicating for which metadata multiple values are allowed.

In the last version of the last version of VOResource, I had defined what 
I call "list elements", eg. <SUBJECT> whose content was a list of values 
which looked something like:

   <SUBJECT>
     <item>...</item>
     <item>...</item>
     <item>...</item>
   </SUBJECT>

After our experience with the prototype registry, we decided it was better 
to just say...

   <SUBJECT>...</SUBJECT>
   <SUBJECT>...</SUBJECT>
   <SUBJECT>...</SUBJECT>

Tony is okay with this style, too, so that's where I expect to see us 
going.  

cheers,
