Hi Chris,
About your last proposal for the name of the TransformID tag, I agree in principle, but an ACES’ XML namespace is in place in AMF, therefore the real tag is already <aces:transformID>.
Instead than modifying this in AMF, I suggest to allow ACES XML namespace in CLF (at least optionally), which harmonizes CLF and AMF name tags, currently existing with different names for similar or identical purposes (like the acesTransformId / TransformID discrepancy that you correctly spotted).
