The following changes will only be implemented if a new major version of ABCD under a new namespace will be published. Ideally this will involve a far more modular approach towards TDWG standards (XML or otherwise), so the changes proposed below should be understood as notes rather than concrete steps to be taken. In any case, a major version change for ABCD is not expected before 2009.
