title: Python lxml objectify - How to create elements with a dash
body: <p>I have a need to use lxml's objectify module to create some xml elements that have a dash in them. For example:</p>
  
  <pre><code>&lt;program-id&gt;$Id: myFile.py 3519 2012-07-17 13:37:20Z $&lt;/program-id&gt;
  &lt;formatter-txt&gt;basic format&lt;/formatter-txt&gt;
  </code></pre>
  
  <p>I can't find any references online about how to do this and when I try to just do it in Python, it's a syntax error. Any help would be appreciated.</p>
