Would it be feasible to include a generic ulp file which sets the expected ulps into the 
target ulp files that add or override such settings? That way most ulp files could be 
significantly reduced and only targets with special formats may need to have more 
entries. Also this would make it clearer when there are anomalies and possible
ulp errors that need to be fixed.
