You start with 100% interoperability with an HTML 4 document; even HTML
2.0 user agents are able to render the document in an appropriate manner
since HTML 4 was designed to be downwards compatible with existing
browsers. You _reduce_ interoperability when writing invalid code; you
rely on the error recovering behaivour of the implementations you have
tested your page with. I recommend reading through the archives of
related mailing lists or newgroups, you'll see a lot of people
complaining on what NN6/IE6/Opera5 make of their pages that "worked" in
horribly broken NN4 or alike. That was caused each time by writing
invalid code.

Where's the problem? If there is a problem, I doubt you've written
"good" HTML, even though it might be valid, but feel free to point
at examples.
