Type: Boolean
The didUnderstand property of the JadeWebServiceSoapHeader class specifies whether a mandatory SOAP header has been understood as part of processing the request. A mandatory SOAP request has the value of the mustUnderstand property set to true.
If the header is understood, your code should set the value of the didUnderstand property to true. If the header is not understood, a SOAP Must Understand error is returned as the response.
