A form session represents a single browser window, usually as a separate tab within the browser.
Each one of these browser windows can be executing a separate instance of a form, and each one of these form instances
maintains its own state data independent of the others. This is achieved by giving each window a distinct
form session context, each one of which is identified by a form session identifier.
An Http session can contain any number of form sessions.
Attributes can be added to the form session in the same way as for the Http session.
