Yes it is. The InstantReality loader can handle data encoded in CData-blocks since beta7
The count-field is optional:

        <IndexedTriangleSet>
          <fieldValue count="3" name="index">
              0 1 2
          </fieldValue>
          <Coordinate>
            <fieldValue count="9" name="point">
                0 0 0, 1 0 0, 0 1 0
            </fieldValue>
          </Coordinate>
          <Color>
            <fieldValue count="9" name="color">
                0 0 1, 1 0 0, 0 1 0
            </fieldValue>
          </Color>
        </IndexedTriangleSet>
