+  <gml:remarks>This definition was derived from the example E.4.1 in OGC Abstract Specification in Topic 2 "Definition of a Temporal CRS in which axis quantity is DateTime" (https://docs.ogc.org/as/18-005r4/18-005r4.html#118). Since GML 3.2 implements an older model for coordinate reference systems, the information in Topic 2 has been mapped to the XML schema of GML 3.2. A Well-Known-Text or PROJJSON representation would support encoding the CRS definition according to the current version of Topic 2.</gml:remarks>
