Description:
The purpose of this amendment is to correct an omission in the requirements for coordinate metadata. CRS identification may be through either a full description or through reference to a full description in a register of geodetic parameters (ISO 19111:2019, 7.2). Coordinate epoch is required to be given with a coordinate set when those coordinates are referenced to a dynamic coordinate reference system. This requirement is described in the UML through constraints in the CoordinateMetadata class. A constraint applying when CRS identification is through reference to a register has been added to the description of the data model.
