Ok, so using that I could look at each attribute as it was read and test
isSpecified. Whenever it returned false, I have "discovered" a default
value and could save it.  I guess I was hoping for a more direct way to
discover the defaults - this relies on reading an existing XML file in
which each attribute is defaulted at least once.  It would be useless if I
had built the tree programatically and then went to output it.  What is
really needed is to have the schema available through some API.
