This is an interesting article by Rodney Decker.
http://www.ntresources.com/documents/InspirationTranslation.pdf
In it he clears up some misunderstandings about translations, namely that:
1)Dynamic equivalence is not the same as Functional equivalence (they are often confused as the same thing).
2)Formal equivalence and Functional equivalence are not mutually exclusive - all translations include both.
Its a good read,
