Why don't you have function "notEmpty"? This would be useful when combined with "allAttributes". I can't see any way, with your current set of functions, to determine that all of a set of attributes are not empty, using the "allAttributes" function. You have "isNull" and "notNull", why don't you have "notEmpty"? Paul Nahay [email protected]
