/** Demo action that uses componentized input / output layer. In order

* they should instead use components to access their inputs and
* outputs. Available components include request parameters,
* attributes, headers, and session attributes. Which component to use
* can be specified upon setup via "input-module" and
* "output-module" tags through the name attribute.
*
* This particular action copies all available parameters obtained
* from the input component to the output component or, if a specific
* parameter is specified through parameter-name, just one parameter.
