Example using XPath

For example, an enveloped signature on the rest of the document:

  <Document id="Full">

    <Signature xmlns:dsig="...">

      <SignedInfo>

        <Reference Id="#Full">

          <Transform Algorithm="..">

            <XPath>not(ancestor-or-self::dsig:Signature)</XPath>

          </Transform>

        </Reference>

        ...

      </SignedInfo>

    </Signature>

    ...

  </Document>
