title: Status of the "marker" keyword in Jinja
body: <p>I was looking though the <a href="http://jinja.pocoo.org/docs/templates/" rel="nofollow">templating documentation for Jinja</a> and noticed that the example does not use the <code>marker</code> keyword in the base template, nor is it used later on in the documentation. However if you look <a href="http://wsgiarea.pocoo.org/jinja/docs/inheritance.html" rel="nofollow">here</a>, <code>marker</code> is used in the example with <code>block</code>.</p>
  
  <p>Why is that? Is <code>marker</code> deprecated? Is one doc more up to date than the other?</p>
