title: SAML Signature Tag Name Standard
body: <p>Shouldn't the SAML Signature be always <code>&lt;ds:Signature &gt;&lt;/ds:Signature&gt;</code>...  I have noticed some Idp use <code>&lt;Signature&gt;</code> and some use <code>&lt;ds:Signature&gt;</code></p>
  <p>In C# I am trying to get the Signature node using.</p>
  <pre><code>XmlNodeList nodeList = samlDoc.GetElementsByTagName(&quot;ds:Signature&quot;);
  </code></pre>
  <p>It fails when the Signature tag starts with <code>&lt;Signature&gt;</code> without <code>ds:</code> prefix. Is there anything that I am missing here?</p>
