The WSDL is correct, however item is a sequence, just look into the WSDL and you will see it.
If you define your array manually, like this
soap/startProcess/processWebParameter/Parameter/item/Name
then you have defined your parameter wrong. You can do the following two things:
1. Define your parameter by defining a data type
soap/startProcess/processWebParameter/Parameter/item and provide an appropriate data type or ANY if your structure is polymorphic.
2. Define your parameter by defining each array element manually.
soap/startProcess/processWebParameter/Parameter/item[0]/Name myName
soap/startProcess/processWebParameter/Parameter/item[0]/Value/StringValue someStringValue
soap/startProcess/processWebParameter/Parameter/item[1]/Name myName2
soap/startProcess/processWebParameter/Parameter/item[1]/Value/StringValue someStringValue2
soap/startProcess/processWebParameter/Parameter/item[9999999]/Name myName9999999
soap/startProcess/processWebParameter/Parameter/item[9999999]/Value/StringValue someStringValue9999999
