If you haven't been touched by the HTML5 bug, now that XHTML 2.0 is out for the count, you are sure to encounter it between now and 2022, when it is slated to become the recommendation. Tools that work with the spec (or at least as much of it as it can) at this stage of it's infancy seems to be just trickling out of the tubes we call the internet.
I have found this post on the Visual Web Developer Blog where they provide the schema files to get HTML5 to work with Visual Studio 2008 and Visual Web Developer Express, however they don't provide DOM2 updates for scripting. Nor do they provide the same xsd files for Microsoft Expression Web 3.0.
The html5.zip attachment has within it a couple of .reg files to update the registry. Taking a quick peek at those I was able to find the corresponding keys for Expression but to make it work I had to add a blank doctype and dtd to the registry which doesn't really work as html5 is without a dtd. I was able to get the doctype and schema to show up in the app, but the doctype didn't validate like within Visual Studio. Sigh.
If anyone knows how to add the HTML5 doctype and schema to the Expression Web applications please post instructions somewhere and send me a link.
