Every message in GP Travel HUB system requires the following elements:

1.2.1. soap:Envelope

A SOAP message is an ordinary XML document containing the following elements:
Envelope* − Defines the start and the end of the message.
Header − Contains any optional attributes of the message used in processing the message, either at an intermediary point or at the ultimate end-point.
Body* − Contains the XML data comprising the message being sent.
