Bold: Attribute or child element is required. (m): Child element can be used multiple times.

Description:

Used to render features according to the value in a specified field. Based on this field, a value map can be created to classify data. This is useful when different types of data are stored in the same layer.

Restrictions:

None

Notes:

Within the same value map, different types of symbols can be used. As an example, if a value map is done on a point layer, some points could be SIMPLEMARKERSYMBOLs, some points could be RASTERMARKERSYMBOLs, and some points could be TRUETYPEMARKERSYMBOLs.
If the same symbol type is used throughout a value map, different attribute values can be used. For example, with SIMPLEPOLYGONSYMBOL some polygons can be solid while others cross diagonally.
For more information on using renderers, see Using ArcXML Renderers.
