says what the root element is and if I wanted multiple possible roots
I would need multiple start elements.
But if a choice element under start does the same thing it is much
clearer to do it that way.
Anyways I cleaned up the schema a bit as Norman suggested.
Now does it do what I intend is the question.
I am attaching the newest version tell me if this is any better.
Thanks
Aaron
