I think it's bug in specification html5 because there no information about Preferred and alternate style sheets. Where is in html5 specification defenition and description Preferred and alternate style sheets? Or mabye some text like "defenition Preferred and alternate style sheets watch in html4 specification"? In Candidate Recommendation html 5.1 also no information about defenition and description Preferred and alternate style sheets. Information have only in html4 (14.3 External style sheets)
