Ain't that the truth! :)

I don't see > this as a good thing. Class values that have no semantic meaning often force to reader to read through the stylesheets to try and figure out what the code is doing. A use of semantic class name could be: <span class="email">me(a)example.com</span> HTML doesn't provide an EMAIL element. It does provide generic element and it does provide a way to make that element belong to a class. Taking semantic class to the next level would be formalization of specific class names, such as how to represent email address. That's basically what microformats does. Microformats makes it possible to, say, write a function `hCardToJSON(div)`, and have that take a div and create and return an object that has the vcard properties. -- Garrett comp.lang.javascript FAQ: http://jibbering.com/faq/

It's not meta-data - it's an arbitrary grouping reference that means whatever you need it to mean. That *is* its purpose. Presumably you wrote the HTML, so complaining that you can't then determine the datamodel (?) by evaluating the stylesheet (?) is a straw man argument.
