I want to implement the microdata on my site which is not using HTML5 yet, it uses
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
I'm planning to convert it to HTML5 soon. But for now I need to implement rich snippets, some simple things like for example:
<div itemscope itemtype="http://schema.org/Event">
Come hear the <span itemprop="name">Tiny Tim Tribute Band</span> in
<span itemprop="location" itemscope itemtype="http://schema.org/Place">
<span itemprop="name">Regency Theater</span>
</span>
</div>
Of course it will not validate in W3C validator. But are there any other problems that I should expect? Will my site render correctly in modern browsers? And what about older browsers like IE7?
I want to emphasize that this is only a temporary solution and site will be soon converted to HTML5.
