Thanks! I was going to look in more detail on native 
xml databases, but this comment of yours has saved me 
some time. Our application does process documents at
run time. Once a document is processed, it is gone and
thrown away and the app looks for the next document to
arrive and process. So obviously indexing, etc of
databases will not be of much help. There is probably
only one situation where it might make sense to use a
native xml db... when a document to be loaded is so
large to load into memory. So i will have to make my
application configurable to use a native xml database
in cases where it expects large size documents and use
an xquery in-memory processor like saxon by default.
