/**
 * Use this Mapper if you have an alias field (e.g. "path_segment" or "alias") in your TCA setup along
 * a DB table.
 *
 * This mapper solves two issues:
 *
 * 1. It allows to reduce configuration for typical mapper scenarios by just using the
 *    Mapper name as registered and use "autoconfiguration" for table names and field names.
 * 2. It allows to use "fallback handling" which is only available in TYPO3 v12.1
 *    see https://review.typo3.org/c/Packages/TYPO3.CMS/+/76545 to have our News plugin
 *    manage the optional parameter for a news detail page, when a news was not found.
 *    For v12 setups, the fallbackValue is automatically set to "null" to keep the same functionality
 *    as in v11 with this news mapper.
 *
 * @deprecated File is not used by news extension anymore and will be removed with version 12
