Can I Use Multiple ItemProps in a Span Tag for schema.org Rich Snippets?

Question

The usual HTML way would be to use one attribute and separate several values with space characters.

Looking into the Microdata specification, you’ll notice that this is the case for the itemprop attribute, too:

The itemprop attribute, if specified, must have a value that is an unordered set of unique space-separated tokens […]

So this should be correct:

<div itemscope itemtype="http://schema.org/Person">
  I live and work in <span itemprop="homeLocation workLocation">New York</span>
</div>

(Note: If using itemprop values as CSS selector, use [att~=val] instead of [att=val].)
