message that is generated. This is not an optional field;
rather, it is mandatory in the communications between
the client and the web service. faultActor specifies
which node caused a fault. Although this field would
provide some additional information related to who
caused the fault at hand, this field is optional. The detail
element provides application-specific error messages;
that is, this element is populated with information
provided by the application. SOAP fault messages can
contain a variety of faultCode options, which indicate
what errors were generated as well as potentially who
caused each error (the sender or receiver). Table 6-5 lists
the available SOAP fault codes and their associated use
cases.

This is a child element of the SOAP header. If this
attribute is set, any information that was not understood
triggers this fault code.
