What do you mean by this?  When you say "prefix", are you talking
about the input one or the resulting one?  If the returned one, what 
does it mean for it to be a URI reference--I thought it would just be
a string that replaces the prefix in the original.  When you say
"absolute with the current base URI", current where--in the catalog
(where it was found as a right hand side) or in the original document?
