> Its currently not possible for Form subclasses to override and implement custom business and cross-field validation logic in the #validate method, because the validate method is invoked *before* the Field values are processed and bound to request values.
> Proposed solution is to rename the current Form.validate() method to Form.validateFileUpload (because that is what is currently does) and introduce a new empty validate method which subclasses can override. This is consistent with the approach taken by Field which also provide an empty validate method which subclasses can implement.
