In that case, validator.w3.org will need a software upgrade. It is  
totally unreasonable to expect an SGML validator to be suitable for  
HTML5 conformance checking.

If the validator (with upgraded software) sees that doctype, it can  
dispatch to an HTML5 mode.

Either HTML 6 will be compatible so that it doesn't need to tell  
itself apart from HTML5. If the people who define HTML 6 in the  
future don't have the good sense to make their spec compatible,  
surely we can trust them to have the good sense to introduce a  
version discriminator then.
