      ISSUE-508 (Table 5)

      o The text indeed required clarification: "core structures have
        their names and parameters highlighted in bold in the second
        column (prov-n representation); expanded structures are not
        represented with a bold font."
      o Indentation of subconcepts had been considered by the editors.
        While it appears beneficial to see Revision, Quotation, and
        Primary Source indented below Derivation, this would lead to
        confusion elsewhere in the table:
          + Plans (in component 3) are subtype of Entity, but entities
            belong to component 1. Indenting Plan under another concept
            would therefore be misleading.
          + Person/Organization/SoftwareAgent could be indented below
            agents. However, our preference is to list core structures
            first, before expanded structures.
          + Finally, Influence could be see as super-relation of many
            relations, but, again, they are spread across components,
            and Influence is regarded as an expanded structures.
      o Overall, there are multiple, conflicting ways of organizing
        table 5. We feel that this order of structures allows components
        to be exposed and core structures to be presented first, without
        attempting to expose a hierarchy of types, which would require
        an entirely different layout.
      o PROV-DM follows the syntax specified by PROV-N. Regarding the
        style of encoding of attributes, this issue is already raised
        against the PROV-N document (issue-533).
