[UPDATE] minor update in order to avoid limitation on parameters type passed to operation when the value must be an Enumeration value (test case : http://graphical.weather.gov/xml/DWMLgen/wsdl/ndfdXML.wsdl, NDFDgen($_latitude,$_longitude,$_product,$_startTime,$_endTime,$_unit,MyndfdStructWeatherParametersType $_myndfdStructWeatherParametersType) instead of NDFDgen($_latitude,$_longitude,MyndfdEnumProductType $_myndfdEnumProductType,$_startTime,$_endTime,MyndfdEnumUnitType $_myndfdEnumUnitType,MyndfdStructWeatherParametersType $_myndfdStructWeatherParametersType))
