qandaentry — A question/answer set within a QandASet
A QandAEntry is an entry in a
               QandASet. Each QandAEntry
               defines a Question and (possibly) its
               Answer or Answers.
               
            
Since V4.2, the preferred way to associate a revision history with
               a QandAEntry is in the BlockInfo.
               The use of RevHistory directly in QandAEntry
               is deprecated.
