 These are good questions but  they apply even if the schema is included and
processed.  If I change a schema so as to change a defaulted attribute value,
what should you do about those documents I've already processed?  The question
is no different.

What, you mean it's better to leave information out of a document and require
a processor to refer to another document to recover it?
