No, but it's feedback we can give to the PF Working Group.

We're here to change the Web :-)

The ARIA spec could have a built-in list of prefixes, too, rather like 
the data-* attributes in HTML 5, where the prefix "data-" is pre-
registered.

It's useful to anyone processing a document who understand something 
about the context and domain.

This is the same argument we had about XML on the Web -- what use is a 
Florbl element if no-oneknows what it means? Well, usually the 
Florbelists know. But how do other people find out? And how does a 
search engine display a Florblin in a result snippet?

So it might be that some form of subclassing approach would work --
  role="abstract.wsj"
