plain old xml considered harmful

(This article is a stub, feel free to expand upon it)

The plain old xml approach has already been tried by *numerous* others since 1998 and has failed on the Web.

OTOH, XHTML + semantic class names has seen widespread adoption among the web authoring/design/IA/publishing community. Microformats is leveraging the approach that is both working better and frankly dominating in practice on the Web.

See also namespaces considered harmful.

XML elements are limited to only one "name" and thus only one meaning, whereas the class attribute is a space separated set of names and can thus capture multiple meanings, providing a much more flexible semantic structure for authors, and greatly aiding in following DRY.

There are 1000s more web authors/developers that write/understand (X)HTML + semantic class names + CSS as compared to the number of folks that write/understand either plain or namespaced XML.

It's the publishers that matter, not the programmers. To put it another way, programmers can solve problems once and share open source. Publishers have to keep solving markup/publishing problems for content and design numerous times continuously, and have much less chance of being able to share their solutions. That, plus the fact that there are many more web designers than programmers, plus simple economics, means the best solution is to optimize for ease of publishing, and let iterative open source solve the programming problems.
