title: What are the arguments of ElementTree.SubElement used for?
body: <p>I have looked at the documentation here:</p>
  
  <p><a href="http://docs.python.org/dev/library/xml.etree.elementtree.html#xml.etree.ElementTree.SubElement" rel="noreferrer">http://docs.python.org/dev/library/xml.etree.elementtree.html#xml.etree.ElementTree.SubElement</a></p>
  
  <p>The parent and tag argument seems clear enough, but what format do I put the attribute name and value in? I couldn't find any previous example. What format is the extra** argument?</p>
  
  <p>I receive and error for trying to call the SubElement itself, saying that it is not defined. Thank you.</p>
