Looks like we are heading toward same goal via different mental
track.  The word 'document' invokes too many preconceived notions
to be used in this context, I believe.  XML stream is more like it.
XML stream that changes its structure over time requires dynamic
schema with ability to redefine, augment, remove schema fragments.

Implementation wise, this is rather simple.  Have client dynamically
download schema fragment-specific handlers.  Security is no problem
since they are restricted to operations on the stream itself.  Java
is a perfect fit for this.

I think dreams are brain farts but I your description *sounds*
better. <g>
