While, I thought this statement is correct and expected the Internet
media-type should be something else (application/xhtml+xml), but as
per w3c, it is not wrong to serve XHTML as text/html (RFC 3236)

Also, have a look at the example given at:

http://www.w3.org/QA/2002/04/Web-Quality

Validating the present output using the validator will give a green
signal too.

Agree to this. Although at the moment it does not cause any harm, it
is a good to be plain HTML when it is a http server.

Éric - HTML5 is not a standard yet and when it becomes one (or much
earlier, when it becomes a de-facto standard), then html producing
stdlib modules should move to it. I don't think we should move faster
than browsers or html client applications.
