title: Response.ContentType = "text/xml" causes XML attributes construct error
body: <p>I have a C# <code>ashx</code> handler that will do some processes and then generate an <code>XML</code> output which should be parsed and sent to the server.</p>
  <p>The problem is when I try to set the context Response to <code>txt/xml</code> it will generate the following error:</p>
  <blockquote>
  <p>This page contains the following errors:</p>
  <p>error on line 1 at column 226: attributes construct error</p>
  <p>Below is a rendering of the page up to the first error</p>
  </blockquote>
  <p>It may look that the problem is with generated <code>XML</code> which may be not formatted well, but I've checked that by getting the output as a string then I used a validator and it was fine.</p>
  <p>Any suggestions please to figure it out?</p>
  <p>XML Output:</p>
