title: XmlDocument, XmlResolver and www.w3.org
body: <p>One of my users had a single error while opening a file (I'm using standard xml 1.0):</p>
  
  <pre><code>The remote name could not be resolved: 'www.w3.org'
  </code></pre>
  
  <p>I found a post here in <a href="https://stackoverflow.com/questions/217841/net-autogenerated-web-service-client-how-do-i-avoid-requesting-schemas-from-w3o">StackOverflow</a> that deals with this and it suggest setting the XmlResolver property to null. I've tried this, and all my documents still seem to load fine. However, the last thing I want is to break the file-reading mechanism of my app, so is it actually safe to disable the resolver?</p>
