HTML5 Postal Address Microdata

HTML & CSS
1

I’m a little confused about setting up HTML5 Microdata for a postal address.

If I wanted to wrap an address in microdata, would I use:

Version 1


<div itemscope itemtype="http://data-vocabulary.org/Organization"> 
   <div itemprop="address" itemscope itemtype="http://data-vocabulary.org/Address">
     <span itemprop="street-address">123 Fake St</span>, 
     <span itemprop="locality">Philadelphia</span>, 
     <span itemprop="region">PA</span> 
     <span itemprop="postal-code">12345</span>
   </div><! -- END ITEMPROP DIV --->
 
   Call us at: <span itemprop="tel">555-555-5555</span>

</div><! -- END ITEMSCOPE DIV --->

or

Version 2


<div itemprop="address" itemscope itemtype="http://data-vocabulary.org/Address">
     <span itemprop="street-address">123 Fake St</span>, 
     <span itemprop="locality">Philadelphia</span>, 
     <span itemprop="region">PA</span> 
     <span itemprop="postal-code">12345</span>
</div><! -- END ITEMPROP DIV --->
 
 Call us at: <span itemprop="tel">555-555-5555</span>
