My understanding of that paragraph has always been that the two
specializations are mandated (I mean their definitions) -but- it
doesn't require the definition of the members of the primary template 
(only their declarations are described).  And in effect, there is no
meaningful way to define them without making extra-assumptions that
have proven in the past not always to meet all users' expectations.
