        <description>This relation is used to identify the engineering telemetry
                   items in engineering files by a name that is descriptive.
                   The name has a four character prefix that indicates the 
                   shuttle mnemonic that corresponds to the telemetry 
                   definition. The mnemonic may be assigned to more than one 
                   CCS telemetry item because of the use in different 
                   telemetry formats. In general when two telemetry items have
                   the same meaning and raw values, the lower numerical value
                   is used. </description>
