I believe this is already part of the recommendation:

"class = cdata-list [CS]
   This attribute assigns a class name or set of class names to an element.
Any number of elements may be assigned the same class name or names.
Multiple class names must be separated by white space characters."

Unless I'm misunderstanding your post.
