If tweaks are arbitrary code though, the user could just do this themself. Anyway, putting a tag on anything in Heqet would be hard, and it poses problems with the "semantic" nature of heqet data: what if you tagged a time signature, but then proceeded it with music in the same meter. Would you print the signature?
So: just have a \keepWith tag (of "edition") thingy in the standard template, and let the precocious lilypond user take advantage of them if they wish.
