Re: using the data* attribute to identify element sub roles

Hi Ansel,

use cases, yes.

the use cases I had in mind is that currently the definitions of some
elements have differing uses:

article can idenity a 1000 word essay, a 100 word summary of said essay and
a 5 word comment on the same essay, but there is no method defined to
idenitfy the different uses. If there was a defined method, a range of
software could make use of it such as search engines and assistive
technology.
