w3c Error: Attribute role not allowed on element label at this point.

[woolyseal]

The validation from w3c is throwing an Error with the following part in the common.py:

_opener_markup_template = (
u'<input id="navitem-{uid}" type="checkbox" class="opener" />'
u'<label for="navitem-{uid}" role="button" aria-label="{title}"></label>' # noqa: E 501
)

The Error says:
Error: Attribute role not allowed on element label at this point.

Is there any use for this "role" in the label? If not, I would fix this.

I just did a fix and commited this in the branch iss259

The point of that role is for people who need to use screen readers to browse the site.
It provides context so they know to expect an action when they click it.

@bmos - Yes, I understand that there should be explaining attributes on it - but the "role" attributes seems a bit off for that. It should most likely be an aria-role or something like that
