CC2538: Smart Energy Certification required Clusters

Part Number:CC2538

Using CC2538 and TI Z-Stack Energy 1.1.0 to build a device like an in-home display to get meter readings from an electrical meter.

Our device is currently working connecting to the C2538 dev kit board set up as a coordinator/meter with the ZigBee security test certificates installed. 

In discussing with the certification , we understand (from the lab and the ZigBee spec)   that we need to support these clusters:  Basic,  Key Establishment and Simple Metering.   

Cannot find specific reference to "Basic" cluster in the TI docs. Does TI call this something else?

Thanks.
