 There are even languages, which only have rules of one category (e.g. `category/xml/errorprone.xml`).
 
 You can find the information about available rules in the generated rule documentation, available

+In order to help migrate to the new category scheme, the new name for the old, deprecated rule names will

+rule names will keep working throughout PMD 6. You can upgrade to PMD 6 without the immediate need
+to migrate your current ruleset. That backwards compatibility will be maintained until PMD 7.0.0 is released.
