To me, external validation is only useful in some rare situations. I often see validation as 'business validation' (for most uses, validation goes beyond checking if a field is required), and find it often too bloated when externalized (XML). I find the doExecute and doValidate combination easy to read, you can directly see which business logic in doExecute needs which business validation in doValidate.
