IMO, this is one of several evidences that choice of XML as the envelope 
format is not ideal unless you reinvent things.   It works well for a 
set of small tightly intertwined modules, but for large independent 
ones, XML and tools do not fit the desired processing models, because 
XML is not so good at isolation.
