"No schema definition for '%s' (namespace '%s') in parent '%s'"
*Cause: The schema definition for the parent node being processed does
not allow for the specified child node in its content model.
Note that any typecasting via xsi:type must occur before the
schema definitions for the new type can be used.
*Action: Only insert elements and attributes declared in the schema.
Check to make sure that xsi:type (if used) is specified first.
