In particular, what happens if someone attaches USING ROLLBACK to an EXIT that does not lead from inside to outside a BEGIN/EXCEPTION block?
I'm not sure which case you're envisioning. A label is required, and the label must be that of a BEGIN block with an EXCEPTION block if USING ROLLBACK is specified. If that doesn't answer your question, could try and explain (perhaps in the form of an example) which problem you're seeing?
