Redefine plays no role in this scenario.
You are trying to restrict a content model of
StudyEventRef+
with
StudyEventRef+|tdm:TrialArm....
This is not allowed. The restriction must validate a subset of the
documents validated by the base type.
As far as being able to validate documents ok, I think maybe the
validator doesn't have access to the redefining Schema or something,
validation should of course fail.
Hope this helps,
Radu
