The term "freestanding entity" refers to things that aren't entities.
It's confusing for "freestanding entities" to be two things (declarations and macro definitions), neither of which are entities. Declarations may declare entities, they are not entities themselves. Given this definition, p6/7/8 makes no sense. A namespace can't be a freestanding entity since it's neither a declaration nor a macro definition.
N.B. LWG 3753 already changed what's in the CD.
