2.1.55 [W3C-HTML52] Section 22.214.171.124. Constraint validation
V0197: No list of elements is returned
The specification states:
... Constraint validation When the user agent is required to statically validate the constraints of form element form, it must run the following steps, which return either a positive result (all the controls in the form are valid) or a negative result (there are invalid controls) along with a (possibly empty) list of elements that are invalid and for which no script has claimed responsibility: ... 7. Return a negative result with the list of elements in the unhandled invalid controls list.
No list of elements is returned.
