Hi all, I have noticed, that for dr3d objects, for example dr3d:sphere, their attributes are optional. But when this attributes are missing, then neither size nor position of the object is known. Even when a unit size 1.0 is assumed, both a position ranges [-0.5;0.5] or [0.0;1.0] make sense. Do you agree, that the specification should give a default value at least for those attributes, that determine size and position? Or should those attributes be changed to be mandantory; is that possible at all? Kind regards Regina
