SOAP Message Structure (SDK SOAP API)

A typical SOAP message has the following skeleton:

<?xml version="1.0"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2001/12/soap-envelope">
  <soap:Header>
    ...
  </soap:Header>
  <soap:Body>
    ...
    <soap:Fault>
      ...
    </soap:Fault>
  </soap:Body>
</soap:Envelope>

This message structure is used both in SOAP requests and SOAP responses.

The root element of a SOAP message is the Envelope XML element. This element contains the following other elements:

• Header (optional). Contains the header information.
• Body. Contains call and response information. This body element can optionally contain a Fault element, which contains information about errors that occurred while processing the SOAP message.

The Envelope element can specify one or more namespace reference attributes. These attributes have the following format:

xmlns:namespace
