The 'class' attribute is only useful in stylesheets or when converting to
another DTD, from my understanding. Arena and emacs-w3 use the class
attribute to be able to specify style information across tags, like:
doc.important: font.family=courier
doc.important: font.size += 5
doc.important: color.text=blue
Then you can use: <h1 class=important>, <a class=important>, etc.

People have been doing this for a long time.
