Defaults are bad when they are in a DTD, and the document is read by a 
validating XML parser (which seems to be the case for the v2 code).

If we move away from DTDs the "defaulting" doesn't affect the parsing 
anymore, and thus would be purely for documentation.

So we need to decide what our position with respect to DTDs is...
