Salesforce Compilation errors on generating apex class from WSDL - salesforce

Question

When I am trying to generate Apex classes from the below WSDL file I am getting the
The following generated class(es) have compilation errors:
Error: testxyzCom
Error: unexpected token: 'limit' at 7:23
The generated class is also given below. I already have some experience in Salesforce and as far as I remember if a WSDL document contains an Apex reserved word, the word is appended with _x when the Apex class is generated. For example, limit in a WSDL document converts to limit_x in the generated Apex class. But this is not happening in above case please explain. Please help me out.
The WSDL file

I've had a similar issue recently with a WSDL that generated an APEX class using the reserved keyword 'long'.
I don't think wsdl2apex is smart enough to add a suffix to reserved keywords as you suggest.
Can you do it by hand to the generated class?
In createOpurtunityData_element
public Integer limit_x;
In TestWSDL
public String[] createOpurtunityData(String[] keys,String[] values,Integer limit_x) {
request_x.limit_x = limit_x;
I'm not 100% sure how the call to WebServiceCallout.invoke will handle this change though. If you can, it would be easier to update the web service and WSDL so it doesn't use a APEX keyword.
