Thank you. Your "Pxp_reader.combine" solution worked for me. (Editing the DTD 
worked too, but I want to avoid that.) 

Was the way I was trying to do things originally sensible? Or is what you have 
shown my here how I should have done things from the start?

I think I understand the first part of what was happening (file resolution is 
applicable to PUBLIC ids that provide filenames, the "~alt" resolver is only 
used if the default resolver is inapplicable), but I still don't understand 
why the directory information gets lost, though.
