CRD Client USCDI 4

This statement defines the expected capabilities of systems wishing to conform to the ''CRD Client'' role for USCDI 4 (US-Core 7.9.0). This role is responsible for initiating CDS Hooks calls and consuming received decision support. It is *also* responsible for returning the data requested by the CRD Server needed to provide that decision support. This capability statement does not define the CDS Hooks capabilities as there is no standard way to do that yet. Instead, it focuses on the 'server' capabilities needed to respond to CRD Server queries. These capabilities are based on US Core.
