title: How do I set namespace attributes on an XElement
body: <p>I need to add the following attributes to an XElement:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;xmlns="http://www.mysite.com/myresource" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.mysite.com/myresource TheResource.xsd"&gt;
  </code></pre>
  
  <p>Adding them as an XAttribute doesn't work because of the ":" and I'm sure is not the right way anyways. How do I add these on there?</p>
