	yes, that's maybe better.

	i was affraid of defining it this way, because there are a lot of
extra
	elements needed. but these elements help a lot in a better
	structuring, so it's maybe good to be forced to use them.

	for example, it also solves the problem the "running text pattern"
solves,
	but in a more natural way, i think.
