I. The HD enables the transmission of informa\on for any site to act as an assigning authority (on a local or user-defined basis), even if it technically does not have the right to issue new ID's within an iden\fica\on scheme. II. HD which have defined third component (defined UID type) must be unique within the series of ID's defined by that component. III. The HD is used in fields that in earlier versions of HL7 used the IS data type. Thus, a single component HD (only the first component valued) will look like a
simple data type for older systems expec\ng a single component in the place of the HD data type. A. I, II and III. B. I and II. C. I and III. D. II and III.
