True.

One last try at a workable solution whilst adhering to the c14n
specification:- re-use the same namespace prefix from the SOAP header.

<ns:Envelope xmlns:ns="http://schemas.xmlsoap.org/soap/envelope/">
 <ns:Body>
  ...
  <Contract xmlns="&foo;">
   <ns:Signature xmlns:ns="&dsig;">...</ns:Signature>
  </Contract>
 </ns:Body>
</ns:Envelope>

I think the namespace prefix should ideally be a descriptive name which
makes this solution less than elegant.  But perhaps it satisfies your
current requirement?
