Type	Name	Comment
SdaiServerContext	serverContextId	Context identification, from edmiDefineServerContext
SdaiInstance	instanceId	A numeric instanceID that uniquely identifies the instance of interest in the remote _
SdaiEntity	entityId	The numeric entityID that uniquely identifies the entity definition instance in a dictionary model in the remote EDMdatabase
SdaiBoolean	isInstanceOf	A variable that will receive TRUE if the instance given in argument <instanceId> is of the instance type given in the argument <entityId>. Otherwise, FALSE will be returned.
SdaiInvocationId	edmiInvocationId	Currently not used.
