title: I am confused about SOAP namespaces
body: <p>I am learning about SOAP implementation and have become somewhat confused regarding the appropriate namespace URI for a SOAP 1.2 Envelope.  </p>
  
  <p>The <a href="http://www.w3.org/TR/soap12-part1" rel="noreferrer">w3c specification for SOAP</a> refers to the <code>"http://www.w3.org/2003/05/soap-envelope"</code> namespace.  However, I have seen other examples that refer to the <code>"http://schemas.xmlsoap.org/soap/envelope/"</code> namespace.  </p>
  
  <p>It seems to me that one or the other namespace should be used.  Which of these two is the correct namespace URI to use?</p>
