You have to look at this from a design point of view. Of course I do not
want users to do that. But conceptually it is the same thing: a
classical bookmark "marks" the content starting at a certain point up to
the end. So it can be stored in the same way which is important since it
makes working with the information much simpler.

I never want them to be. I do not want to store the excerpt
independently. The point is to mark the excerpt (we might need a better
name) but let it be a fully qualified IE in the database as compared to
some artificial bookmark instance.

I don't know what you mean here.

I suppose you mean a reference into a book which is not finished and can
change?
If so this could be handled by either leaving the end of the excerpt
open or define a special marker which means "up to the end".

I think that is pretty much what I mean. I never wanted to extract
information from the original resource. I only want to reference it via
nie:hasLogicalPart, ie. properly describe which part of the text or
image we mean.
