         The <span style="font-family:monospace"><span class="command"><strong>FormBroker</strong></span></span> package creates instances of 
         objects representing a form data description. These objects offer a 
         simple interface of methods meant to validate and control data 
         as typically posted through an HTML form, 
         thus data represented through the association of form variables 
         with their values as returned, for example, 
         by the <span style="font-family:monospace"><span class="command"><strong>::rivet::load_response</strong></span></span> command

      	The <span style="font-family:monospace"><span class="command"><strong>FormBroker</strong></span></span> package is still experimental. 
      	Basic functionalities and interface are not likely to change but
      	internal details and implementation could be redesigned
      	in future releases. More specifically the external validator mechanism
      	could be improved with the purpose of shielding the <span style="font-family:monospace"><span class="command"><strong>FormBroker</strong></span></span>
      	internals from a data validation procedure.
