ContextItemTypeInteger1

Essentially a Representation ID. We are talking about an ID of an abstract class because ContextItem values can correspond to:

  • NumericRepresentationValues (e.g., FSA Area of a field)
  • EnumeratedRepresentationValues (e.g., PLSS Prime Meridians)
  • String Representations (e.g., US Driver's License number)
ValueString0..1Optional because container ContextItems (e.g., PLSS) would not have a Value.
