title: Savon 2.1 adding attributes to message XML tags
body: <p>I am currently trying to add an atribute to one of the xml elements I am generating for the SOAP  request I am making.</p>
  
  <p>I see savon has an attributes hash, but that only adds attributes to the soap message tag. Is there an equivalent feature that I have not come across for the generated XML in the message body?</p>
  
  <p>IE say I have a tag in my message body </p>
  
  <pre><code>    &lt;ClientData&gt;&lt;/ClientData&gt;
  </code></pre>
  
  <p>I would like to be able to be able to something like</p>
  
  <pre><code>     &lt;ClientData id=1&gt;&lt;/ClientData&gt;
  </code></pre>
  
  <p>Is this possible with using Savon hash syntax?</p>
