Design an XML format for representing the menu structure of a computer program. A menu can contain any of the following in any number and order:

• another menu (i.e., a submenu),
• a menu item,
• a separator.

Both menus and menu items must have a name that must be specified using an attribute.

Create a DTD for the format, and also an XML document to demonstrate the use of the format that describes the following menu structure:

• Main:
  • File:
    • New
      • XML
      • JSON
      • Text
    • Open
    • Save
    • Save as
    • [separator]
    • Exit
  • Edit:
    • Undo
    • Redo
    • [separator]
    • Cut
    • Copy
    • Paste
