For example, it is intuitive to do this:
<input type="text" disabled="false" />
and to someone's dismay, it won't be disabled.
<input type="text" disabled="true" />
the form will start as disabled (yay!). The new user might be tempted to do
Things like that should work (though it doesn't). It would make HTML better (easier to learn).
Proposal: if the value of a
checked, etc, property is anything other than
"false", make it behave as
true, otherwise make it behave a
false, not relying strictly on the existence of the property. These types of changes to HTML would make HTML more friendly.
