I agree with Simon Fernley I hope HTML5 does not force us to remove quotes and have properties with no values.

Lines like:
<input id=name name=name type=text placeholder=“First and last name” required autofocus>

I would rather they where more like:
<input id=“name” name=“name” type=“text” placeholder=“First and last name” required=“true” autofocus=“true”>

I think even HTML should be valid XML and should be strict.
Back to read more about HTML5 can check I can still use quotes on properties of HTML elements.
