I assume someone will at some point write documentation about grub
scripting language. You are free to start the documentation project.
Just to point it out, grub scripting language works like entering
commands in the prompt. Its just a sequence of multiple commands.

Those below are an example what menu definition would look in grub
scripting language:

Depending what you mean by attribute set. In case you mean visual look,
then that was the plan you could eg. define menuitem and if you do not
have more stricter definitions then that would be used for every
menuitem. In case you mean cloning menu hierarchy under other name, then
that is not planned (and I do not even see a need for it).

There is old text menu, and that will be replaced with the new design
when its development starts.

See above about grub scripting language.
