Missing schema.org property bestRating & worstRating

When I validate the HTML content from my new template via the Google Structure Data testing tool here, it found the following issue:

Your rating value was out of the default range, you must provide best and worst values.

The related section in the HTML code is:

<div class="kt-ratings-overview" itemprop="aggregateRating" itemscope itemtype="http://schema.org/AggregateRating"><div class="kt-ratings-stars" data-kt-ratings-overall data-score="0"></div><span class="kt-ratings-title">Rated 0 out of 5 based on 0 votes</span><meta itemprop="ratingValue" content="0" /><meta itemprop="reviewCount" content="0" /></div>

Can you please fix that in the next version?

Thanks

P.S.
Changing \com_komento\ratings\overall.php and adding the following:

	.'<meta itemprop="bestRating" content="5" />'

	.'<meta itemprop="worstRating" content="0" />'

Should sort that out I think.
