The <SRS-LIST> element defines the projections of the map and the services used by the map. SRS refers to the spatial reference system code that is understood by OGC web services. The SRS codes are defined by the European Petroleum Survey Group, and have names like "EPSG:4326".

The <MAP>, <WMS-SERVICE>, and <WMS-LAYER> elements contain srs related attributes. The value of those attributes must match the name of one of the entries in the <SRS-LIST> sub-elements.

Note that the map configuration file elements must appear in sequence, and the <SRS-LIST> element must be the first sub-element in the map configuration XML file. For best results, validate your XML against the schema for this file format.
