I also think inline is better, even though it adds redundancy.

The 'n' is probably not needed in practice even though conceptually
Mojca is right.

One way around that (and the 'n' issue) is to do something like this:

     arguments = {
             ["label_arg"] = {
                 type = label,
             },
             ["filename_arg"] = {
                 type = file,
             },
             ["settings_arg"] = {
                 type = settings,
                 comment = "short comment for this option",
                 description = "long description for this option",
                 inherit = { "useexternalfigure", 'settings_arg' }

             },
             ["parent_arg"] = {
                 type = parent,
                 comment = "short comment for this option",
                 description = "long description for this option"
             },
         },
       variants = {  -- just an example
           { "filename_arg" },
           { "label_arg", "filename_arg" },
           { "label_arg", "filename_arg", "settings_arg" },
           { "filename_arg", "parent_arg" },

         }
     },

but I am not sure this is really better ?

Best wishes,
