For an Adam/Eve DSEL in C++ we used this syntax:
sheet save_file =
 "save_file" == sheet
   {
      interface == section
      {
        var{"file_name"} == [](arg_map args){ return any(""); },
        var{"file_type"} == "txt",
        (var{"password"} <= (var{"file_type"}, var{"password1"})) ==
            [](arg_map args)
            {
              return args.get<string>("file_type") == "txt" ? any("") : args["password1"];
            }
        // more constraints
      },
      output == section
      {
        // more constraints
      },
      invariant == section
      {
        // more constraints
      }
   };
Interesting.  At Adobe we had a DSEL that looked something like (from memory):

   dialog(name = "Clipping Path")
   [
        column(child_horizontal = align_fill)
        [
            popup(name = "Path:", bind = &path, items = list
               [
                   item(name = "None", value = empty),
                   item(name =  "Path 1", value = 1),
                   item(name = "Path 2", value = 2)
               ]),
            edit_number(name = "Flatness:", digits = 9, bind = &flatness)
        ],
        button(name = "OK", dephault = true, bind = &result)
    ];

Or something like that.
Of course we didn't have C++0x at the time.
