title: flash pro to flash builder migration of documentclass
body: <p>I am migrating a bunch of projects which were built in Flash Pro to Flash Builder....</p>
  
  <p>The basic structure of those projects were an FLA which has a DocumentClass. That DocumentClass referenced various items on the stage...</p>
  
  <p>Is there any way to duplicate this in Flash Builder? I know I can just embed the swc or swf and then access items via ThatDisplayObject.itemToAccess, but calls from outside will no longer work. I.e. if this project is loaded by a container, which then calls SubProject.itemToAccess...</p>
  
  <p>Or must I change all the mappings, or set getters/settings on the new Flash Builder project so that outside calls will access the items?</p>
