Easy. Select the version of HTML you want to test conformance with in the  
validator/conformance checker. This doesn't belong in HTML.

Use latest by default, don't check which version is specified (because no  
version should be specified).

As said; default.

Yup, I agree.

If it's even possible to include version information, it will only cause  
confusion and damage. What we need is a sound mechanism for extension and  
error correction, so future versions of HTML can be parsed and rendered in  
older UA's without breakage and thus allow future versions of HTML to be  
backward-compatible. I agree that may not be the situation today, but it  
should be a goal for this WG to make it so for tomorrow.
