Data structure for an individual datum within a class.

typedef struct _DCIDataAttr {
  uint32             size;     /*  Total structure size. */
  uint32             datumId;  /*  The individual metric identifier. */
  uint32             type;     /*  Data type for this metric. */

  uint32             flags;    /*  Metric characteristics. */

} DCIDataAttr;

typedef   DCIDataAttr   * DCIDataAttr ;

The DCIDataAttr structure is used to describe an individual datum within a class. All of the data attribute structures are kept at the class type node along with the rest of the class attribute structures.
