typedef struct _DCIClassId {
  uint32            size;        /*  Size of the fixed and variable length portions. */
  UMAArrayDescr     identifier;  /*  Descriptor for the variable-length identifier. */
  UMAVarLenData     data;        /*  Start of the data section. */
} DCIClassId;

typedef   DCIClassId   * DCIClassId ;
