### <a name="PerformanceClass"></a>PerformanceClass

This DE denotes the ability of an ITS-S to provide up-to-date information.

 A performance class value is used to describe age of data. The semantic defintion of the values are out of scope of the present document 

This DE denotes the ability of an ITS-S to provide information fullfilling additional requirements.

 A performance class value is used to describe characteristics of data. The semantic defintion of the values are out of scope of the present document 

 and should be subject to profiling.

  The value shall be set to:

 The following options are available:

* _deltaPositions_ of type [**DeltaPositions**](#DeltaPositions) <br>

* deltaPositions<br>

  an ordered sequence of delta geographical positions with respect to the previous position, with latitude and longitude,

   with the first instance referring to the reference position and with the order implicitly defining a direction associated with the polygonal line.

* _deltaPositionsWithAltitude_ of type [**DeltaReferencePositions**](#DeltaReferencePositions) <br>

* deltaPositionsWithAltitude<br>

  an ordered sequence of delta geographical positions with respect to the previous position, with latitude, longitude and altitude,

   with the first instance referring to the reference position and with the order implicitly defining a direction associated with the polygonal line.

* _absolutePositions_ of type [**GeoPositionsWAltitude**](#GeoPositionsWAltitude) <br>

* absolutePositions<br>

  a sequence of absolute geographical positions, with latitude and longitude.

* _absolutePositionsWithAltitude_ of type [**GeoPositionsWoAltitude**](#GeoPositionsWoAltitude) <br>

* absolutePositionsWithAltitude<br>

  a sequence of absolute geographical positions, with latitude, longitude and altitude.
