Everyone else is saying that errormessage is inherently different to 
description. If that really is how it's meant to be according to the 
ARIA spec (I disagree, but that's not relevant here), then mapping it to 
description (even with an attribute) is a big hack. You can't have it 
both ways; it's either just a specialisation of description or it's not. 
Several people now say it's not the former, so it must be the latter. 
And if it *is* the former, then it should be included as part of the 
description text as well.

FWIW, I don't like this whle thing at all, but it seems wrong to me that 
the ARIA spec says it's not at all a description and the a11y specs say 
it is. Personally, I think the ARIA spec *should* treat it as just an 
extension of description, but I've already made that point and it 
doesn't seem popular.
