Translation codes

The chapter headings in this index are colour coded to indicate the extent of the translation process. The more extensive the review, the more confidence the reader will be able to place in the translation. 'Reviewed' means that another competent translator has checked the work section by section. 'Authorised' means that a member of a specialist panel has reviewed the whole translation, and approved it.
