title: Creating function for hybris template engine
body: <p>I need to link a product with editorial content from another platform (wordpress by example).
  Is it possible to create function in the template engine (like in smarty) which will detect a specific tag ? </p>
  
  <p>For example, if in my product description there is this king of tag <code>{% post_related=ID %}</code>
  then my function in the template engine would replace that tag by html code or call a webservice....</p>
  
  <p>Also, what template engine is use in Hybris ?</p>
  
  <p>Thanks</p>
