The comment fields in xmldb editor are very useful for documenting your database tables and fields. Comments on indices might occasionally be useful. However the comments on foreign keys are always useless in my experience as it is completely clear from the existing comments on the fields. I would like these particular comment boxes to be removed in order to reduce confusion.

For example I have a field called userid with the following comment: 'User who created this version. May be null if the version was created by the system, such as when the wiki is initialised from a template.' I added a foreign-key reference to the user table and it asked me for a comment, but what else am I going to say?
