Defining Name/Value Mappings

A provider can define a list of name/value pairs that consumers use to map integer values to strings. The name/value pairs can map integer values to strings or bit values bit values to strings; each value corresponds to a string value. Use mappings on integer data items that contain enumeration values.

Consumers can use the value map to retrieve the string associated with a value and display it instead of displaying the integer or bit value. To define an integer value map, use the valueMap and map elements. To define a bit value map, use the bitmap and map elements.

The following example shows how to define a value map and a bitmap. You must specify the map's name attribute. For each name/value pair, you must specify the value and message attribute.
