Before the administrative task can be removed, another action is required to ask for task removal on the server.
The action type to call back to a JSON server action is 'serverAction'.
When parameters were introduced earlier, parameter lists were also mentioned. A 'parameterList' contains a series of 'parameter' elements used to assign local parameters. Keep in mind that all local and shared parameters are shipped across to the server automatically so it is a good idea not to put anything too large into a shared parameter.
Note: There is slight distinction between the parameter types 'raw' and 'fixed'. A type 'fixed' will perform a parameter marker substitution whereas a type of 'raw' will not.
