XBUSXMLMessage represents messages in the xBus specific XML-format. It is very useful when a message leaves the context of the xBus and reenters again, e.g. it is buffered in a message queue or send to another instance of the xBus via HTTP.

The first part (XBUS_Call) contains the header fields common to all message types. They are explained here.

10 - 17:

The second part (XBUS_Data) contains either the request or the response data of the message.

11 - 16:

In this example, the response data is a wrapped XML document. The XMLWrapperTransformer wraps arbitrary string messages into a XBUSXMLMessage by packing them into a CDATA section, to avoid the interpretation of the data by the XML parser.
