Web service with JSON result

When I create a web service that returns JSON and I use the example from the help file:

SELECT top 3

   emp.EmployeeID,

   so.CustomerID,

   so.Region

FROM Employees AS emp KEY JOIN SalesOrders AS so WHERE emp.EmployeeID <= 195

ORDER BY 1

FOR JSON AUTO;

The webservice returns:

"forjson(512,'emp',forxml_sep(),'EmployeeID',jsontab."1",'so',forxml_sep(),'CustomerID',jsontab."2",'Region',jsontab."3")": "[{"emp":{"EmployeeID":129,"so":[{"CustomerID":107,"Region":"Eastern"},{"CustomerID":119,"Region":"Western"},{"CustomerID":131,"Region":"Eastern"}]}}]"

How can I get rid of the header "forjson...." and how can I get rid of the " around the data section?

TIA
