Re: Multiple types in RDFa vs. in Microdata

Hi Stéphane, 
thanks!

In fact, I think the better pattern would be to use the "link" element:

> 
> <div itemscope itemtype="http://www.foo.com/Type1" itemid="http://acme.org/things#1>
>  <link itemprop="http://www.w3.org/1999/02/22-rdf-syntax-ns#type" href="http://www.foo.com/Type2" />
> </div>
