<bookevent>
The <bookevent> element indicates a general event in the
         publication history of a book. This is an appropriate element for specialization if
         the
         current set of specific book event types does not meet your needs. If an element already
         exists to describe a specific type of event, such as <reviewed>,
         <edited>, or <approved>, use that element  instead.
