* An action that will create a form instance, let it handle the current request (and

* validation failed. In both cases, the created form instance is stored in a request attribute,
* so that it can be picked up later on by other components.

* <ul>
* <li><strong>form-definition</strong>: filename (URL) pointing to the form definition file
* <li><strong>attribute-name</strong>: name of the request attribute in which the form instance should be stored
