That's strange, I get a different error with Xerces 1.4.1:

   [Error] test.xml:2:45: Unknown base type  for type ScoreAndNoScoreList.
   [Error] test.xml:2:45: Schema error: cos-list-of-atomic: The itemType
must have
   a {variety} of atomic or union (in which case all the {member type
definitions}
   must be atomic).

I think it's a bug.  XSV does accept it when the instance is valid, but for
some reason crashes when you have an invalid value in the list (apparently
another bug).
