As you can see, the <Header> element is only a container for other elements, the application-specific header entry elements. Any parameters generated for an operation in this SOAP message appear in the <Body> element in much the same way.
In this case, the SOAP header contains two header entries, named q1:OrderInfoID and t:Transaction (where q1: and t: are namespace prefixes). Each of these elements has a series of attributes and contains one or more child elements. The <q1:OrderInfoID> element contains one child element named uuid, and the <t:Transaction> element contains two child elements, named t:TransID and t:SubID. All of these element names are application-defined.
