I was more thinking of avoiding DOM altogether. The streaming example
is about creating smaller DOM trees that get translated to the object
model. I guess going directly to the object model would increase the
read speed. Another advantage with the XSD/e hybrid approach is that
it is easier to cut out an element of a certain schema type. With the
"XSD streaming example" approach it might be more difficult,
especially if an element name could occur at different places in the
xml tree but have different schema types.

Yes, that is true.

Just to clarify the thoughts I had. I think it is the GPL version 3
software that doesn't allow itself be linked to software that can't be
"relicensed" to GPL version 3 ( for instance GPL version 2 software ).
That would also include XSD as the FLOSS exception doesn't give
permission to "relicense" XSD to GPL version 3.
