[Bug 12148] I strongly believe disallowing 'true' and 'false' in boolean attributes will cause significant confusion in the future. Already, you can find respected web developers incorrectly referring to attributes as true and false. For instance: http://blog.getif

Status: Rejected
Change Description: no spec change
Rationale: 

I agree that the current design is poor. This is actually why I encourage the
use of value-less boolean attributes (<input disabled> rather than <input
disabled=something>).

However, changing it is a non-starter. It would be an absolutely huge change to
the specification and to implementations — the sheer number of places that
test for attribute presence that would need to change to test for attribute
value is simply phenomenal. It would be a very high-risk change, since it's
quite likely that there are pages that accidentally say things like
checked=false but mean it to be checked. It would lead to several years of pain
for millions of authors, as browsers slowly migrate from one behaviour to
another. It would mean massive efforts updating HTML documentation, books,
tutorials, etc, the world over.
