Dave Morris made this point to me at the VOTech meeting in Strasbourg
last week, but I'm not sure I was thinking very clearly about it at
the time.  A question which occurs to me now: does VOSpace require 
a single data format per file (or entry, or whatever the correct 
term is), or can a single file be labelled with multiple different 
data format URIs at the same time?
