A.2.2 RCL_OpcAmlMetaModel library

The AML best practice is for all SystemUnitClasses to implement at least one Role. The RCL_OpcAmlMetaModel library contains one RoleClass UaBaseRole that all OPC UA-derived SUCs shall implement. The UaBaseRole derives from the standard AutomationMLBaseRoleClassLib/AutomationMLBaseRole.
