The schema is nowhere near complete -- there are no top-level element
declarations, so there is nothing to validate with. I think you need
to learn more about XML Schema (start with the Primer [1]) and about
MPEG-7's use of schemas -- for instance it may be that there are
multiple schema documents in the ISO spec., and you have not gotten
all the necessary ones.
