Differences between SOAP 1.1 and SOAP 1.2

This section describes differences between a SOAP 1.1 request and SOAP 1.2 request for NumberToWords Web service provided by dataaccess.com.

Remember that my goal is to use SOAP::Lite to send SOAP 1.2 request to the dataaccess.com server.

Before writing the client program, let's compare the SOAP 1.1 request with the SOAP 1.2 request provided at: dataaccess.com/webservicesserver/NumberConversion.wso?op=NumberToWords:

SOAP 1.1 request: 

POST /webservicesserver/NumberConversion.wso HTTP/1.1
Host: www.dataaccess.com
Content-Type: text/xml; charset=utf-8
Content-Length: length 

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <NumberToWords xmlns="http://www.dataaccess.com/webservicesserver/">
      <ubiNum>unsignedLong</ubiNum>
    </NumberToWords>
  </soap:Body>
</soap:Envelope>


SOAP 1.2 request: 

POST /webservicesserver/NumberConversion.wso HTTP/1.1
Host: www.dataaccess.com
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length 

<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">
  <soap12:Body>
    <NumberToWords xmlns="http://www.dataaccess.com/webservicesserver/">
      <ubiNum>unsignedLong</ubiNum>
    </NumberToWords>
  </soap12:Body>
</soap12:Envelope>

I see 2 differences:

Note that the SOAP 1.1 request example does not include the SOAPAction header line as suggested by the SOAP 1.1 standard. This is ok as long as the dataaccess.com server does not require it.
