<img src="pic.png" itemprop="img" itempropvalue="pic.jpg">

What is the value of the property "img"? Is it resolved as a URL or is it  
a plain text property? (src and href attributes are resolved as URLs in  
microdata, so itemValue would be something like  
"http://example.com/pic.png" if itempropvalue were not there.)


<div itemscope itemtype=review>
   <p itemprop=location itemscope itemtype=geo  
     Located at <span itemprop=lat>37.3610</span>, <span

What is the value of the property "location"? Is it a plain text property  
"37.3610,-122.0250" or the subitem with type "geo" and two properties  
"lat" and "long"?

None of these questions would arise with a <data> element, simply because  
you don't have the extra attribute to overload itemValue with.
