(3)To ensure that the provisions are presented in a clear and rational manner, consistent with the principle of better regulation, it is appropriate to recast the structure and the wording of the Directive although this will not, in principle, bring about material changes in the existing legislation. A small number of substantive amendments are however inherent to the recasting exercise and should nevertheless be made. Where such changes are made, these are listed exhaustively in the provisions governing transposition and entry into force.
