Giving priority to something (noun)
is a regular character or custom or habit, not a specific thing to do. This is the difference between geround and "to do".Geround is more like a noun to describe a thing. "to do" is more like a verb for a specific action. The same can be said to the role of diploma. You are not to use it right now or in near future for that specific purpose. It is one of the diploma's functions.
