> The spec says:
> "While not mandatory, it is considered a good parctice to split the core constraint from the not null constraint validation ..."
> As examples we have @Email and @Length, but would the same not apply for @NotEmpty. From a programmers point of view I think @NotEmpty should return true for null values. However, one could argue that from a GUI perspective it would not make sense to get to different validation messages. In fact, a user does not know what it means that the value cannot be null. However, any decent GUI/web framework will make sure that a string value will always be passed as empty string when nothing is entered by the user.
