title: Typo3 - Enable microdata attributes itemprop, itemscope and itemtype in RTE
body: <p>To enable <a href="http://en.wikipedia.org/wiki/Microdata_%28HTML%29" rel="nofollow">microdata</a> in RTE i think i have to add the attributes for each tag in RTE config in the root pages TSconfig.</p>
  
  <p>There are many examples, how to add a attribute for a tag, e.g. xml:lang:</p>
  
  <pre><code>RTE.default.proc {
    entryHTMLparser_db = 1
    entryHTMLparser_db.allowTags &lt; RTE.default.proc.allowTags
    entryHTMLparser_db.tags.div.allowedAttribs = xml:lang
  } 
  </code></pre>
  
  <p>This works very fine.</p>
  
  <p>But when i try to adopt this for itemprop, itemscope and itemtype:</p>
  
  <pre><code>RTE.default.proc {
    entryHTMLparser_db = 1
    entryHTMLparser_db.allowTags &lt; RTE.default.proc.allowTags
    entryHTMLparser_db.tags.div.allowedAttribs = itemprop, itemscope, itemtype
  } 
  </code></pre>
  
  <p>
  it's not working.
  Does somebody know how to add microdata attributes in RTE?</p>
