I guess it depends on what the purpose of validating markup is.
That may validate to an SGML DTD, but it's not conforming HTML 4.01
(it's not valid HTML 4.01) and for what it's worth the HTML 4.01
specification specifically warns against extending text/html in this manner:
For <time> specifically, the benefits of a custom DTD over just using
Henri Sivonen's HTML5 validator is unclear to me:
I'd be wary of using a hybrid of HTML 4.01, RDfa, and HTML5 when neither
RDFa nor HTML5 have been finalized yet, and when HTML5 is going to
determine how browsers actually parse all text/html. What if HTML5 ends
up specifying something in a way that is incompatible with the hybrid?
