public interface: NoParameters
Marker interface to incidate no auto setting of parameters.
This marker interface should be implemented by actions that do not want any
request parameters set on them automatically (by the ParametersInterceptor).
This may be useful if one is using the action tag and want to supply
the parameters to the action manually using the param tag.
It may also be useful if one for security reasons wants to make sure that
parameters cannot be set by malicious users.
