Technically, OBX for VMR Data SECTIONSECTIOHTTPAccessControlAllowOriginManagerN, STRUCTURAL and COLLECTION are optional as the structure is implied by the dotted decimal structured OBX-4 Observation sub-ID. However, including these OBX segments can be useful to viewers of the atomic data but non-essential for computed interpretation of the actual content.

For items in the table with occurrences with an upper bound > 1 (eg e.g. 0..*) that element will have "RepeatOf[]" specified in the OBX-4 Observation sub-ID. The "RepeatOf[]" must be substituted with the repeat index integer of the element/structural/section group. All child elements for the repeat index must be prefixed with this sub-ID value.
For example, the first instance of a past illness the OBX-4 sub-ID must be 1.2.1.1, for the second 1.2.1.2.
Based on this the Past Illness OBXes for the first illness must have a OBX-4 sub-ID value of 1.2.1.1.1, and for the second illness, the OBX-4 sub-ID value must be 1.2.1.2.1.
