indeed, and I think the error is to think about line breaks as something
that affects the scene graph's topology. It does (and should) not.
Of course, the scene may include special markers that indicate the
possibility of a break (in Fresco98 these are called 'discretionaries',
I believe), but the actual break is performed each time the scene is
layed out...
