Description

   The INSERT ELEMENT command places one or more elements or groups
   into one or more groups. The groups must already exist. When you
   use the INSERT ELEMENT command with a group name, you insert the
   contents of the group. For example, if you insert group A into
   group B by using the INSERT ELEMENT command, group B will contain
   the contents of group A at the time of the insertion transaction.
   If the contents of group A change at a later time, the contents of
   group B are not affected. To insert a group into another group,
   use the INSERT GROUP command.
