With regard to microdata I was wondering if the elements must be exactly like the examples (http://support.google.com/webmasters/bin/answer.py?hl=en&answer=176035) or that Google/Bing look if the itemprop attributes occur on certain elements.
e.g. could I replace this:
<div itemprop="name">some text</div>
<span itemprop="name">some text</span>
Without affecting its functionality?
