xsdl generateduniqueprefix

Hi Experts,

we have used wsdl to generate a soure sturcture. In this code,

wsdl:part xmlns:generateduniqueprefix0=""

what does it means?

code:

<wsdl:message name="EmployeePhone">

http://rapal.fi/optimaze/elisa" name="EmployeePhone" element="generateduniqueprefix0:EmployeePhone"/>

</wsdl:message>

Thanks
