The Directory Record is based on the specification of Section F.3. It is identified by a Directory Record Type of Value "HL7 STRUC DOC".
Table F.5-33 lists the set of keys with their associated Types for such a Directory Record Type. This Directory Record shall be used to reference an HL7 Structured Document and any of its referenced content stored on the interchange media but not encapsulated in a DICOM SOP Instance. The document may be encoded as an XML document with in-line multimedia content, or may be encoded in a multi-part MIME wrapper (see PS3.10). This type of Directory Record may reference a Lower-Level Directory Entity that includes one or more Directory Records as defined in Table F.4-1.
