Xmlns: ds SOAP header for each element to generate an XML signature

I have rtfm, but I still have problems. I am re-reading the manual, but posting here because what I am doing is not working. I was provided with the xsd and wsdl file for the SOAP service. I have never implemented a client that requires digital signatures. I wrote a soaphandler to change the title of the envelope, but I cannot understand what I'm doing wrong.

The soap consumer told me that the canoncalization xml message passed to the signature generation should look like this:

<ds:SignedInfo xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
  <ds:CanonicalizationMethod Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#" xmlns:ds="http://www.w3.org/2000/09/xmldsig#"></ds:CanonicalizationMethod>
  <ds:SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#rsa-sha1" xmlns:ds="http://www.w3.org/2000/09/xmldsig#"></ds:SignatureMethod>
  <ds:Reference URI="#secinfo" xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
    <ds:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1" xmlns:ds="http://www.w3.org/2000/09/xmldsig#"></ds:DigestMethod>
    <ds:DigestValue xmlns:ds="http://www.w3.org/2000/09/xmldsig#">ZwOJboUtw1RlDspibqbyaWrKIog=</ds:DigestValue>
    <ds:Transforms xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
      <ds:Transform Algorithm="http://www.w3.org/TR/1999/REC-xpath-19991116" xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
        <ds:XPath xmlns:ds="http://www.w3.org/2000/09/xmldsig#">//*[@id='secinfo']/child::*/text()</ds:XPath>
      </ds:Transform>
    </ds:Transforms>
  </ds:Reference>
</ds:SignedInfo>

The xml I created looks something like this:

<ds:SignedInfo xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
  <ds:CanonicalizationMethod Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"></ds:CanonicalizationMethod>
  <ds:SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#rsa-sha1"></ds:SignatureMethod>
  <ds:Reference URI="#secinfo">
    <ds:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1"></ds:DigestMethod>
    <ds:DigestValue>ZwOJboUtw1RlDspibqbyaWrKIog=</ds:DigestValue>
    <ds:Transforms>
      <ds:Transform Algorithm="http://www.w3.org/TR/1999/REC-xpath-19991116">
        <ds:XPath>//*[@id='secinfo']/child::*/text()</ds:XPath>
      </ds:Transform>
    </ds:Transforms>
  </ds:Reference>
</ds:SignedInfo>
