I like the idea of having some mechanism to declare defaulting behavior.
such a mechanism is redundant if the DTD is present, but it does make the
instance much easier to author.  On the other hand, it might lead to
confusion if the mechanism is too complicated.

But there can be a difference between what the XML spec says is significant
and what a parser hands to the application.  Witness SP.  I do not think we
need declare what the parser returns, this is should not be an API
discussion group.  We sould declare what is _signicant_.  If a parser does
not pass along insignificant data when the application desires it, that is a
problem with the parser, and the application should use a different parser.
The point of theis discussion is to say that the whitespace is not
significant.. thus the application should only get it if it needs to.  Don't
burden the application, burden the parser, in those cases where the
application demands it.
