Dear Louise,
if by nesting you mean any code-code relationship such structures can get more complex and larger in size than simple term hierarchies.
You can have relatively long causal chains mixed with propositional relations etc. Furthermore, non-hierarchical - even cyclic - sub structures may exist when modeling semantic and episodic knowledge.
I suspect you are considering restrictions for the archive representation language?
