Re: proliferation of reference roles in the dpub aria spec.

AFAIK (and per[1]), the acceptable link type (a.k.a. possible values for @rel) are registered through the microformat wiki page[2]. Do we have enough information on whether this registration mechanism really works well for implementers? How easy/difficult is it to add new @rel values if so required? Just to take examples from this thread, rel=biblioentry is labelled as "dropped" (ie, not to be used), and rel=glossentry is unregistered. I must admit I do not know how [3] functions in practice. And I also do not know how AT's take @rel values into account (if at all).

I do not have any strong opinion, just not clear what the mechanism is in practice…

The Coga task force wants to introduce and aria-destination attribute for links to create standard destinations users would go to to enable consistent style of the UI for familiarity to the user.
