Because it doesn’t, per specification. Quoting:

   The class attribute has several roles in HTML:
       * As a style sheet selector (when an author wishes to assign 
style information to a set of elements).
       * For general purpose processing by user agents.

But that is not the case right now, in HTML 4, and existing content will 
contain nonsensical information in their class attributes, which makes 
them useless to process. A set of values for the class attribute could 
be standardised, but because there’s so much ‘noise’, it can’t be relied 
upon, which makes it quite unreliable and useless from a machine 
processing point of view (which is why they are added in the first place).

I’d say that is the reason new attributes such as @role and @property 
are needed. Those can make a fresh start, and because they are only 
specified when they actually have semantic meaning, a user agent 
(including search engines) can do something with it...
