title: Does HTML5 require an action attribute for forms?
body: <p>I've just run a webpage of mine through the W3C HTML5 validator, and it validates completely, even though the form in it doesn't have an <code>action</code> attribute, which the HTML 4 validator always complains about. Considering the fact that the HTML5 validator is still experimental, is the fact that the form validating despite not having an <code>action</code> attribute a problem with the validator, or has the HTML5 spec changed to not require that attribute any more?</p>
