In this case, you've changed range values, so a simple parsing test like you've done here should be sufficient to work out whether there's something internal to Xj3D that has a difference of opinion on field value ranges. If you were doing something more structural, such as adding nodes or new language constructs, you'd need to go with visual testing.

very good, thanks.  in this recent case i think it is sufficiently tested.

some of the version 3.3 changes are in the 3.3 DTD only.  is Xj3D using
the right version of DTD (3.0 3.1 3.2 3.3) depending on the listed
version of the scene, or is it applying a single DTD to all files?
hopefully it is properly choosing correct DTD prior to validation.

all the best, Don
