Specifying Whether Elements Are Qualified
The ELEMENTQUALIFIED parameter (of your web service) controls the value of the elementFormDefault attribute in the schema of the WSDL. Specifically:
If ELEMENTQUALIFIED is 1, then elementFormDefault is "qualified".
If ELEMENTQUALIFIED is 0, then elementFormDefault is "unqualified".
The default value for this parameter depends on the value of the SoapBodyUse class keyword. See the Class Definition Reference. Normally SoapBodyUse is "literal", which means that ELEMENTQUALIFIED is 1.
For information on the differences between qualified and unqualified elements, as well as examples, see Projecting Objects to XML.
