title: How to split itemscope over multiple HTML elements?
body: <p>I have the following HTML:</p>
  
  <pre><code>&lt;body itemscope itemtype="http://schema.org/WebPage"&gt;
    &lt;header itemscope itemtype="http://schema.org/WPHeader"&gt;
      &lt;nav itemscope itemtype="http://schema.org/SiteNavigationElement"&gt;
      &lt;/nav&gt;
      ...
      &lt;div itemscope itemtype="http://schema.org/Organization" itemref="objectDetails"&gt;
        &lt;span itemprop="name"&gt;Org name&lt;/span&gt;&lt;br&gt;
        &lt;span itemprop="address" itemscope itemtype="http://schema.org/PostalAddress"&gt;
          ...
        &lt;/span&gt;
      &lt;/div&gt;
    &lt;/header&gt;
    &lt;ul itemprop="breadcrumb" itemscope itemtype="http://schema.org/BreadcrumbList"&gt;
      &lt;li itemprop="itemListElement" itemscope itemtype="http://schema.org/ListItem"&gt;..&lt;/li&gt;
      ...
    &lt;/ul&gt;
    &lt;div id="objectDetails"&gt;
      &lt;div itemprop="description"&gt;...&lt;/div&gt;
      &lt;div itemprop="foundingDate"&gt;...&lt;/div&gt;
      ...
    &lt;/div&gt;
  &lt;/body&gt;
  </code></pre>
  
  <p>This web page displays information about one particular organization. Some information about organization should be displayed in a page header, other - in the center of a page. With the help of <code>itemref</code> attribute I can split information about organization and put it on two separate divs. </p>
  
  <p>If I test the above HTML with google structured data testing tool - it extracts info about organization correctly - properties from both divs are shown, but it shows validation error on a WebPage object:</p>
  
  <blockquote>
    <p>The property <code>foundingDate</code> is not recognized by Google for an object of type <code>WebPage</code>.</p>
  </blockquote>
  
  <p>What is the correct way to tell Google that properties that are inside objectDetails div doesn't belong to the outer itemscope (WebPage)? If I add <code>itemscope itemtype="http://schema.org/Organization"</code> to objectDetails div - then Google sees two separate organizations on my WebPage.</p>
