Highlight: Tackle the architecture; integrate the build system with Dojo

• Selected Dojo as the UI toolkit of choice
  
• Packaging and Loading
  

1. How to put XAP app inside of HTML
2. Minimal things you need to do to create XAP app
3. Code size/loading issues
4. Figure out naming scheme for classes/files (package naming)
5. Defining tag -> bridge class mappings in file instead of hardcoding them

• MCOs (managed code objects) and Macros fully functional
  
• Documented and working bridge mechanism -- this is how XAL connects to UI components
