I hadn't noticed the changed definition, but I absolutely agree: The new 
definition is much less clear than the original one. Not only is it much 
more abstract (intentionally so, I assume), but there is no longer a 
reference to the work. Probably, this is supposed to be covered by the 
relationship LRM-R2. But still, it makes it seem as if an expression 
could exist on its own, without a work in the background.
