Will give it a try, thanks. It would work much better than what I'm 
using now (a hacky transformer that gets prefix->namespace mappings 
from external files and plugs them "on the fly" when it gets a null 
or empty nsURI for a qualified start/endElement). Actually, however, 
my problem was in SAX parsing to a SourcePropWritingTransfomer, 
where I got a DOM Namespace error. Will see if your workaround fixex 

Thanks so much,
