A wsdl:binding in a DESCRIPTION MUST refer, in each of its soapbind:header, soapbind:headerfault and soapbind:fault elements, only to wsdl:part element(s) that have been defined using the element attribute. Because faults and headers do not contain parameters, soapbind:fault, soapbind:header and soapbind:headerfault assume, per WSDL 1.1, that the value of the style attribute is 'document'. R2204 requires that all wsdl:part elements with a style attribute whose value is 'document' that are bound to soapbind:body be defined using the element attribute. This requirement does the same for soapbind:fault, soapbind:header and soapbind:headerfault elements.
