      <documentation>
         Used as part of a migration strategy in order to maintain backwards compatibility when changing the id or the version of a facet. Allows one or more aliases to be defined for facet id or version. Once an alias is defined, it will resolve to the actual facet when it appears in project metadata or is referenced in an API call.
