There's nothing nasty about it. And it has nothing to do with markup

You have carefully constructed yourself a problem, alright.

You misspelled "unreliable hack". And from your description, it is obvious
that you are intentionally using invalid markup. So what are you
complaining about when you ask a validator to check and report the
validity of your markup, and it does exactly that?

You are. A validator is neither honest nor dishonest. It simply does what
you ask it to do. The question is: why do you use a validator in the first
place, if you _don't_ want reports from invalid constructs?

Suggested reading on the myths and facts of validation:

Regarding the extra spacing, there is a very simple solution: put
form { margin: 0; }
into your style sheet. If you are worried about the small amount of
browsers that don't support this yet, then it's not a validation problem,
and then the real problem is your page design that relies on details of
layout, instead of being flexible.
