FWIW, I don't believe this personally--I've not seen a single argument 
that I wasn't able to defeat--but it seems like this decision has 
already been made in ARIA. Certainly, NVDA will just be merging it into 
description internally. What I will say is if ARIA views it as being 
fundamentally different (as misguided as I think this is), it seems 
problematic if the accessibility APIs merge it.

That said, one nasty problem with an additional API or relation is that 
we have to call/crawl that additional thing for *every* accessible just 
to find out whether it has an error message. That's kinda ugly from a 
performance perspective; we hurt performance everywhere just to support 
aria-errormessage. Still, I guess this is the best we can have given the 
majority opinion that it is so fundamentally different.

I'm happy with the names you proposed.
