4.7 1246 It is odd. I entered a description for an attribute and left the pop-up default selection and thought there must be some other way in the configuration tool to activate it but I didn't have time to search for it. I created a new major version and published the previous. I didn't really notice the "?" until sometime later and couldn't remember how I did. I couldn't make it happen in the test mode again. I entered several more and when I published that version - Presto! - there they were. They also appear in the new version in test mode after that.
Now that I know that's how it works I can live with it.
