Narrative:
Altitude restriction had been given by ZLA to restrict an IFR departure below the normal assigned altitude. The altitude restriction was missed by the approach controller. Coordination had been made in reference to an overflt that had nothing to do with the altitude restriction for traffic departing. Had center stated why the altitude restriction this could have alerted the approach controller and prevented the violation of airspace.
