In theory you are perfectly right. Each tool has strengths and 
weaknesses and it would
be great to mix and match.

But unless implemented correctly this can yield to a performance 
catastrophe.

Unless ALL tools are implemented to work on the same physical 
representation for
XML, you'll spend all your time copying and converting the data between 
various
physical formats (e..g. one consumes and produces SAX, the other one 
expects a DOM and the
last one wants a JSR 173).

I've been there while in BEA.
