Suppose that function foo is a member of a set S of functions that
operate on numbers. Suppose that one passage states that an error must be
signaled if any function in S is ever given an argument of 17.
Suppose that an apparently conflicting passage states that the consequences
are undefined if foo receives an argument of 17. Then the second passage
(the one specifically about foo) would dominate because the description of
the situational context is the most specific, and it would not be required that
foo signal an error on an argument of 17 even though other functions in
the set S would be required to do so.
