Are they really separate technologies? Is anyone actually planning on using standards compliant HTML5 in isolation, apart from corresponding advanced Javascript and CSS3 features?
It does make sense to use it in isolation, because the HTML5 parsing rules are much more robust against errors, without suffering from the catastrophic failure mode of XHTML. You can use the HTML5 doctype today, and you can validate your code as HTML5 today, and it will work across all common browsers.
