[70] 本当に、なんで HTML の利用者エージェントの適合性を規定しているのでしょうね・・・。
それは HTML の仕様の役目でしょうに・・・。どうしてもそれを規定したいのなら、
HTML4 と Web Linking の両方を実装するUAは rel属性をこう解釈しなければならない、ともっとはっきり定義すれば良いのに。
の Google検索のデータベースを使った調査によると、
要素の利用数第17位が
link
だった。

の注には、 Link を link と同じように扱うと書いてあります。
(が、基底URI の話なので、基底 URI 限定のメモかもしれません。)

If the topic is an XML based feed, publishers SHOULD use embedded link elements as described in Appendix B of Web Linking [RFC5988]. Similarly, for HTML pages, publishers SHOULD use embedded link elements as described in Appendix A of Web Linking [RFC5988].
Since <link> has been limited to being placed in the <head> for many years, some consuming code might only check the <head>. Therefore it is more robust to place the <link> tags only in the HTML <head> rather than in the <body>.

rel=self も rel=hub も認められてないんだよなー。
