Apologies to eveyone for the two stupid errors, one in the question and one in the explanation.
The second answer option should have read "Enterprise and Standard editions". I've asked Steve to correct it. The idea wasn't to list all the editions that support the feature (enterprise, Standard, developer, Evaluation) just to list a set which din't have any that didnýt support it, and I've no idea how I came to put BI in there - when I looked at the question today I was horrified to see it.
The link in the explanation shouldn't have "]" on the end. I've asked Steve to correct thtat too.
Once again I've demonstrated that even when trying to be careful I can mess up posing a QOTD. :blush:
