I am reading the PDF document and ran into the term OID in the section 4.2.11. Array Constructors
However, OID is first defined in Chapter 5. (5.4 System Columns). Is it reasonable to perhaps move the contents of or repeat part of the contents of section 5.4 in sectioln 4.2.11?
Is this unreferenced term that appears earlier than the definition considered a document bug?.
