        tableName: tx_news_domain_model_news
        routeFieldName: path_segment
    requirements:
      page: '\d+'

setup for seo sitemap:

plugin.tx_seo {
   config {
      xmlSitemap {
         sitemaps {
            news {
               provider = TYPO3\CMS\Seo\XmlSitemap\RecordsXmlSitemapDataProvider
               config {
                  table = tx_news_domain_model_news
                  sortField = sorting
                  lastModifiedField = tstamp
                  #additionalWhere = AND (no_index = 0 OR no_follow = 0)
                  pid = 83
                  url {
                     pageId = 84
                     fieldToParameterMap {
                        uid = tx_news_pi1[news]
                     }
                     additionalGetParameters {
                        tx_extension_pi1.controller = News
                        tx_extension_pi1.action = detail
                     }
                     useCacheHash = 1
                  }
               }
            }
         }
      }
   }
}

But url's in sitemap are like: detail?tx_extension_pi1%5Baction%5D=detail&tx_extension_pi1%5Bcontroller%5D=News&tx_news_pi1%5Bnews%5D=1&cHash=30fc7d4bb0d4d32f09d4fe5d3be61728

But they should be like on page detail/news/have-a-nice-url
