I doubt that'll work.  Imagine someone authoring a document; they add a  
citation, and want to run the output transformation again.

The easiest way is instead of sending a single query for each  
distinct-value of the "citekey" key, I somehow send a query that asks  
for all of them at once.
I'm not quite sure who to do that, though.  I know that I want a "for  
$key in $keys return mods:mods[ID='$key']" sort of expression; I just  
don't know how to do that with the key.
