I would prefer not to include it in name and description calculation. Too many things are getting added to the description, and it makes for a messy user experience.

Hey Jamie.

Yeah, we have a description property which is a string. Right now, I don't have a strong feeling either way about whether aria-errormessage's text belongs as part of that value. So if you think it should be there in addition to exposed via the relationship pair, I don't mind.
