It would be a very long list in order to build those and write out all navigation rules. With UML, you can visually see how each one of these elements is connected. You could pick one and then traverse the line to see what items it can navigate. If it can navigate to it here it should be able to do that in the code.

The UML specs is an intricate pile of alternative notations that can drive you crazy. Explore with caution!

In real life, KEEP IT SIMPLE! Don't use "dot notation" and don't use x to denote non-navigability, unless your peers are familiar with it.

Use arrows for navigable associations. People are familiar with it, or if not they're intuitive enough.
