Are you asking to remove the part that says that the declaration is not a definition? That seems like a pretty important statement.

s/cv-qualified/cv/ here seems like a good idea; the current wording can be read as implying:

struct S {
  static const void x; // error, cv-qualified void
  static void y; // ok, cv-unqualified void
};

... which is not the intent.

Yes, that makes sense. It seems that qe usually spell this as \cvqual{cv} \tcode{void}; pull request coming.
