      <comment>The element mapping contains a reference to the permanent wId (attribute original) of a structure, and to the eId (attribute current) such structure had during the time interval included between an initial temporalGroup and a final temporalGroup. This is useful for tracking the evolving ids of documents frequently renumbered (e,g., bills). Every single element whose wId does not match its eId needs to be represented here.</comment>
