That depends on how you define keyword. I don't see why the empty string can't
be defined as a keyword.

That wouldn't be enough  you'd have to go through the entire spec changing
"keyword" to "value", which would make the whole spec much less readable since
the word "value" is used all over the place. In particular, it would be very
confusing because attributes have values whether they're valid values or not,
so we'd have to define some strings as being valid values and have sentences
talking about whether a value is a valid value that maps to a state or not, and
so on. I tried making this edit but had to abandon it because it really hurt

In practice I really don't buy that this is a particularly big problem: there
are only two attributes (contenteditable and spellcheck) that take the empty
string as a keyword; together with the note in question, that means only three
places in the whole spec mention this.
