Just because the developers of WordPress itself put such attention onto XHTML standards compliance doesn’t necessarily mean plugin authors do the same. Even if the author of the theme you use put substantial effort into total compliance, your installed plugins nevertheless have the potential to mess things up.
To raise awareness that there are some plugins out there neglect to follow these established coding practices (“programming grammar,” if you will), I’m publishing a list of plugins that I know of that produce invalid XHTML. (We still like you plugin authors, just fix them please!)
