Of course, you meant just the opposite: the name can is omitted (in
"classic" HTML), when the value is one of the declared enumerated values
of an attribute and no other attribute has such a value that way.

Indeed, i.e. the attribute _names_ input and checked are omitted.
Of course, browsers won't grok this except for the latter, since they only
know a limited number of special cases. Similarly, <h1 center>, no matter
how valid in "classic" HTML, won't work in practice.
