    Rigid body dynamic attribute ambiguity?

    The <dynamic> attribute of rigid body's technique common is not required nor does it have a default value. Should it not have at least one of those? For a rigid body without the dynamic tag, its state is undefined.

    I'm suprised too, I would expect it to be required or at least have a common value.

    In practice, when the mass is zero, an object is <dynamic>false</dynamic>, and when the mass is non-zero, it is <dynamic> true</dynamic>. Then there is still a flag needed to tell wether an object is 'kinematic', which differs for most physics engines.

    Would be good if someone has time to file this as a bug in the COLLADA Schema.
    Thanks,
