Does a type just have 'linkage' other than internal/external linkage?

3.5 [basic.link] paragraph 8 from N4567 says that

... A type is said to have linkage if and only if:

  • it is a class or enumeration type that is named (or has a name for linkage purposes (7.1.3)) and the name has linkage; or
  • ...

which exclusively elaborates on linkage of types—one of the entities that a name can denote. However, it seems that there is no information in this paragraph whether the linkage that a type shall have is internal or external. Is it because there is no need to define it at all, or because it is already defined by other paragraphs?

The type either has linkage, or it doesn't. This paragraph is self-contained: the first half defines the notion of a type having linkage, and the second half describes restrictions on the use of types having no linkage. The notion of linkage of a type is not used anywhere else, as far as I can tell.
