Tapestry should output valid HTML5 when using the HTML5 doctype in templates

When using a HTML5 DocType in a Tapestry template, the textfield component is still rendered with end tags:

Template:
<t:textfield t:id="loginEmail" value="loginEmail" type="email" />

renders as:
<input id="loginEmail" name="loginEmail" type="email"></input>

According to the specs, end tags must not be specified for void elements.
