- Sebastian, I agree that every element can be involved in variation and.... I can only vaguely imagine the tremendous problems for TEI content models, so a compromise would probably be the best!
- Limiting to a problem that, I guess, often happens, when the textual variation is at block-level, it should be encoded with block-level <app>!
Seems more straightforward than all possible alternatives ...
- "normal" TEI user would worry about processing when encoding.
Which tools are available and which techniques you can use may in practice influence your way of encoding ... e.g., xpointer is a powerful standard, but pretty nothing can handle it.
(Big voices are speaking there, forget me if I am saying nonsense :)
