[X3D-Public] containerField is should or must ? largeattributes; compression

[Joe D Williams]

I disagree with count field here

            <fieldValue count="9" name="point">
                0 0 0, 1 0 0, 0 1 0
            </fieldValue>

I think the count should be 3 because point is an MFVec3f.
In order to get the validation in the same way as for attrs, then the 
count if given should match the number of fields expected when trhe 
data was encoded as an attribute.

Thanks and Best Regards,
Joe

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>
