Re: makesOffer should accept Service

Unfortunately, the Google Structured Data Testing Tool will report an error
to you unless you add additional SPAN or DIV to alleviate the ambiguity of
the itemscope or perhaps the properties themselves.  That might be a bug,
but then again, I myself might have a hard time interpreting which
itemscope is actually IN SCOPE within a single <div>.  But, after adding an
extra <span> around the "address", I was able to get nicely extracted data.

<div itemscope itemtype="http://schema.org/Product" >

<div >
  <span itemprop="name">WHITE HOUSE</span>
  <span itemscope itemtype="http://schema.org/Residence"><span
 itemprop="address">1600 Pennsylvania Ave NW, Washington</span>
  </span>
</div>

  <div itemprop="offers" itemscope itemtype="http://schema.org/Offer">
    <span itemprop="price">$110,000,000.00</span>
    <link itemprop="availability" href="http://schema.org/InStock" />In
stock
  </div>

</div>
