This is the normal formatting for Microdata:<div itemscope itemtype=http://schema.org/LocalBusiness><div itemprop=name>some text</div><div itemprop=description>some description</div>    <div itemprop=address itemscope itemtype=http://schema.org/PostalAddress>        <span itemprop=streetAddress>Rosary Arms 12</span>        <span itemprop=postalCode>90210</span>         <span itemprop=addressLocality>Beverly Hills</span>        <span itemprop=addressRegion>San Fransisco</span>         <span itemprop=addressCountry>USA</span>    </div></div>Now, when a users searches for all businesses in San Fransisco, I want to format each result with this Microdata (I'm assuming this is allowed btw and not that Google only accepts 1 Microdata 'instance' on a page).But in the search result of 1 result I have more data than is currently needed for Microdata. For example, I have 3 images per search result, rates of this business, opening hours and much more.Now I was wondering if I can just place this extra data within this microdata without affecting its functionality, for example:<div itemscope itemtype=http://schema.org/LocalBusiness><div itemprop=name>some text</div><div class=businesspreviewthumbs>    <img src=/images/1.png />    <img src=/images/2.png />    <img src=/images/3.png /></div><div class=rates>    <span>Hourrate: $120</span></div><div itemprop=description>some description</div>    <div itemprop=address itemscope itemtype=http://schema.org/PostalAddress>        <span itemprop=streetAddress>Rosary Arms 12</span>        <span itemprop=postalCode>90210</span>         <span itemprop=addressLocality>Beverly Hills</span>        <span itemprop=addressRegion>San Fransisco</span>         <span itemprop=addressCountry>USA</span>    </div>    <div>        <p>Opening hours:<br/>        Monday-Friday: 8AM - 6PM<br/>        Saturday: 10AM - 5PM<br/>        Sunday:Closed<br/>        </p>    </div>      </div>
Can I enrich Microdata format with more non-Microdata data without affecting its functionality?
html5;microdata
Yes!  Parsers only look for the elements not the existence of additional classes or attributes.Go nuts!
