datums.xsd

See ISO/DIS 19136 13.5
The datums schema components can be divided into three logical parts, which define elements and types for XML encoding of the definitions of:
-	Abstract datum
-	Geodetic datums, including ellipsoid and prime meridian
-	Multiple other concrete types of spatial or temporal datums
These schema components encode the Datum packages of the UML Models of ISO 19111 Clause 10 and ISO/DIS 19136 D.3.10.
