mustUnderstand

Type: Boolean

The mustUnderstand property of the JadeWebServiceSoapHeader class specifies whether the SOAP header is mandatory for the Web service consumer recipients to process.

As the value of this property is false by default, the SOAP header is optional.

When you set this property to true at run time to make the SOAP header mandatory, the consumer of the header entry must obey the semantics conveyed by the fully qualified name of the SOAP header and process correctly to those semantics, or it must fail processing the message.

As SOAP headers that must be understood can modify the semantics of their parent or peer headers, those who do not fully understand them cannot ignore the semantics.
