[req] Support for HTML5 validation

[dekimsey]

I know, I know, this would probably a very large set of changes but I thought it needed to be written down.

It would be great if tidyp would support validation of html5.

Then again, it would behoove of me to actually remember this is merely a port. Not the core project.

As a result, I am closing this non-issue.

It's not a port. It's a fork. Who knows, some day we'll do HTML 5.
