Adding a Namespace Object to the XFA Object

Hi,

I'm looking into optimizing the code in my forms. I noticed that, unlike most of the other LiveCycle Objects, the root XFA Object is enumerable and writable, and I was just wondering if anyone knows if it's safe to create my own Namespace Object and add it as a property of the XFA Object. If it is ok to do this, then it would be a great way to store all the form properties... all your Script Objects could point to the same location. I was able to get it to work using the following code:

//create global namespace object

var OBJ = ( function() {

          if ( typeof xfa.OBJ === "undefined" ) {

               xfa.OBJ = {};

          }

          return xfa.OBJ;

     }());

Thanks,

Anthony
