title: Sitecore item guid without curly braces
body: <p>What is the best way to strip/replace the <code>{}</code> characters from the Sitecore item @id output in xslt?</p>
  
  <p>Problem:
  I have to identity certain tags in my html from the <code>id</code> attribute. Using names is dangerous because of the risk of the Sitecore end user typing spaces or illegal characters in the name. </p>
  
  <p>On the other hand using the item id causes the id in the html to say: <code>id="{xxxxxxxx-xxx(...)}</code>, in which case the <code>{}</code> are illegal as characters in html id attribute.</p>
  
  <p>So:
  What is the best way to strip/replace the <code>{}</code> characters from the xslt @id output?</p>
