Cannot use attributes with dashes in them, like 'data-item'

[starrychloe]

This doesn't work:

    .star-rating{title: $rating, data-url: $model->url}

Yields

syntax error, unexpected ':'
    <div <?php echo MtHaml\Runtime::renderAttributes(array(array('class', 'star-rating'), array('title', $rating), MtHaml\Runtime\AttributeList::create((data-url: $model->url))), 'html5', 'UTF-8'); ?>>

Neither does this:

    .star-rating{title: $rating, 'data-url': $model->url}

Yields

syntax error, unexpected ':'
    <div <?php echo MtHaml\Runtime::renderAttributes(array(array('class', 'star-rating'), array('title', $rating), MtHaml\Runtime\AttributeList::create(('data-url': $model->url))), 'html5', 'UTF-8'); ?>>

Got this to work:

    .star-rating{:title => $rating, 'data-url' => $model->url}
