It's not the only the extension, but the relevancy to the extension that hits it badly. No-one in the UK calls a Lawyer an Attorney. I'm not even sure most of us can spell it :P
We have solicitors and barristers. Those terms would get you some good bucks, even in the .org.uk, but seeing as this is a pretty much unused term in a minor extension, my appraisal is a meagre £10-20 at most reseller. Sorry!
