In the meantime there are some important things you can do to prepare yourself for it. As you will learn from this tutorial, XHTML is not very different from HTML 4.01, so bringing your code up to 4.01 standards is a very good start.

XHTML, HTTP accept-header and MIME-type application/xhtml+xml

What’s the Difference Between HTML and XHTML?
If you’ve mastered HTML, you’re 90% of the way towards using XHTML. They’re actually very much the same thing—tag-based markup languages used to display Web pages. The difference is only seen by the people creating the pages (Web designers, programmers, etc.) and focuses on “forgivability”— HTML allows for some ugly code (mixed case tags like
, improperly nested elements, and unclosed tags), while XHTML does not. If you write HTML, it’s probably a good idea to start using XHTML practices anyway. It will take 5 minutes to learn, and it’s just a better way of doing things.Jason, Chris. ChrisJason.com (2006). Articles>Web Design>HTML>XHTML

The weight of these benefits has to be evaluated in the context of your project: Use the right tool for the right job. For a Web designer, starting to use XHTML 1.0 will be helpful in some circumstances and will certainly help you to smoothly negotiate the future. XHTML 1.0 gives a wonderful opportunity to learn about XML languages and their possibilities without having to learn new semantics because you’re working with familiar tags and attributes.
