Now that the development of XHTML 2 is discontinued, should we stick to XHTML 1.0 or move forward to HTML 5 or better prefer the old HTML 4? Let’s set things straight once and for all. In this post we are trying to clear up the confusion, explain what is what and describe what markup language you can use for your web-sites.

Misunderstanding Markup: XHTML 2/HTML 5 Comic Strip

Since the official announcement of W3C to stop working on the development of XHTML 2 in the end of 2009 and increase resources on HTML 5 instead, there has been a lot of confusion and various debates about the “proper”markup language for modern and future web-development. With XHTML 1.0, XHTML 2, HTML 4, HTML 5 and XHTML 5 we have so many languages that it’s really getting hard to keep track!

"XHTML 2 is dead. Long live XHTML …as HTML 5."

The death of XHTML has been greatly exaggerated.

The W3C announced last week that the XHTML 2 Working Group will wrap up at the end of this year. This should have been a straightforward, welcome announcement. Instead it has confused a lot of people who believe that it heralds the end of XHTML—see, for example, the comments on Zeldman’s blog post.
