What would it take for HTML to support XUL functionality. This doesn't need to be HTML used on the Web. Mozilla has great HTML code and new features hit HTML first (sometimes only). So what would we need to add to our HTML codebase to support XUL through XBL:

• Popup support
  • menus and panels
  • tooltips
• Templates
• Better access to native theme data in CSS
• Rich ellipsizing support in text elements
• XUL flex-box model layout in CSS
• Trees
• Listboxes
• Resizers
• Stack/Deck
• XUL presentational attributes (flex, hidden, collapsed, width, height, etc.)
• Prototypes
• Fastload
