The DynamicID structure represents an identifier for a resource of an arbitrary type.
The identifier for a resource whose type is specified by DynamicID.type. When clients pass a value of this structure as a parameter, the field DynamicID.type must contain the actual resource type. When operations return a value of this structure as a result, the field DynamicID.type will contain the actual resource type.
The type of resource being identified (for example com.acme.Person). Services that contain operations for creating and deleting resources typically contain a constant specifying the resource type for the resources being created and deleted. The API metamodel metadata services include a service that allows retrieving all the known resource types.
