3.9 Association role items

The [type] and [role playing topic] properties are both not
optional. Can you clarify why?

Also you write:

"Association role items represent association roles, and may have
the following properties:"

Everywhere else N0396 says "..and have the following properties". Is the
'may' significant here?
