6The spatial-temporal coordinate reference systems schema components are divided into two logical parts. One part defines elements and types for XML encoding of abstract coordinate reference systems definitions. The larger part defines specialized constructs for XML encoding of definitions of the multiple concrete types of spatial-temporal coordinate reference systems.
7These schema components encode the Coordinate Reference System packages of the UML Models of ISO 19111 Clause 8 and ISO/DIS 19136 D.3.10, with the exception of the abstract "SC_CRS" class.
