Yes, I understand that HTML5 tries to be as backwards-compatible as it can
be. But what about future documents? Are you saying that the HTML5 parsing
rules leave no room for a party to generate documents that will 'look wrong'
in a HTML5 browser and 'look right' in that same party's browser?

Because as long as that room exists, and as long as there is a free open
market, there will likely be parties that will try that. When they do, other
parties will feel forced to start applying non-HTML5-specced guesswork again.

Nothing against HTML5. I'm just trying to get a clear picture of just how
much of a difference HTML5 can actually mak; to what extend Ian's description
of what I labelled "guesswork" may actually become reality.
