Here is my first pass at this. I propose the following sentence be added at the end section 8.4:
If you need to track related exceptions (exceptions during exception handling), you should use exception chaining. You can chain exceptions by using the ``from`` clause. Just raise a new exception class or instance from an existing exception. The existing exception will be set as the cause for the new exception.
