As part of the online demo at try.powermapper.com we collect summary statistics about pages scanned by our service. One interesting statistic covers versions of HTML and XHTML in common use. As of September 2016:

HTML Version by Doctype: HTML 5 75%; XHTML 1.0 11%; XHTML 1.1 0%; HTML 4.01 3%


Timeline of web standards: 1994-2010

This diagram shows how web standards have developed since 1994. Originally HTML and related standards were discussed and agreed by a small group of interested parties on a mailing list. Later the W3 was formed, and it put in place increasingly rigorous processes, with increasing amounts of public consultation. While solid process and consultation is a good thing, one striking point is how long it now takes to get W3 standards from Draft to Recommendation status.

In 2006 we converted our site from HTML 4.01 to XHTML 1.0. It seemed like it should be straightforward. After all, we reasoned, XHTML 1.0 is compatible with HTML so it should just be a case of changing the doctype from HTML to XHTML. Wrong.

There are a lot of good reasons for switching to XHTML, but there are some drawbacks as well. Imagine you're responsible for a major e-commerce web site, and you make the decision to migrate the entire site from HTML to XHTML, serving it to standards compliant browsers (like Firefox) using the W3C recommended MIME type application/xhtml+xml. A couple of months after the switch someone types <br> instead of <br/> when making a minor edit to the main site template.
