This highlights one of the issues.  The v3 may or not be derived, and 
telling whether it is will depend on a curious blend of logical 
heuristics, subsequent human evaluation combined with an assessment 
against developing multi-national legal precedents.  At the end of the day 
we may choose to radically include a v3 object where all non-CT-compliant 
tags have been overwritten or removed, or we may conservatively choose to 
remove anything that has a possibility of being tainted by an earlier 
revision.

If the v3 editor can optionally just modify the v1 CT-compliant version of 
the object, then the problem is minimised, and the task simplified.
