Who is talking about substitution? I am not talking about server side
scripting practices as a whole. I said that escaping is no substitution
for using quotes, since one can not expect developers to escape space
characters. That's all.

And I think adding quotes is better handled in the presentation logic,
than in the business logic. It is more the responsibility of the front
end engineer, than of the back end developer.
But it really does not matter. There should be an easy way to enforce
it, no matter what code generates the quotation marks. I don't think
such an enforcement is a panacea to all problems, but it's a small help
for some problems, quite common for rookies, though.
Please do not argue against it on the failed merits of not being able to
substitute indata filtering and output escaping. Those factors are not
part of this equation.

So, you are using python, a language that enforces specific indentation
to define block statements, to say that JSLint has got it all wrong?
lint tool to enforce semi-colons, it makes sense for an HTML conformance
checker to enforce quotation marks.
Always? No, not for boolean attributes and *perhaps* not for attributes
that by design never can take anything but a simple keyword or integer
as a value.
I think I've stated my case by now. So until I hear from Ian (who writes
the spec) or Henri, who is authoring the validator, I think we've
reached the end of this discussion.
