Yes and no. True, the minimum size of SS document is a few kilobytes. When
you consider the minimum that SS documents need in them, I am not sure that
it is easy to do much better. What XML might need boggles my mind, but perhaps
I have a very different spec from you. I would imagine the xml would have to
be interpreted into a temporary for use.

Well that is what COM does in effect. I dont see how that mediates access to the
document though. Two processes want to write the document at once, which implies
some kind of internal structure. OpenDoc and SS both took this approach. Typically
one process will want to increase the size of its portion of the document - in place.
I am first to admit I know little enough about XML but I just cant see how you could
do this.
