   Hi @JWT007,
   
   Thank you for helping us checking our documentation against the automatically-generated plugin reference. We created the plugin reference exactly for this purpose and we are happy you find it useful.
   
   This is a longstanding [LOG4J2-696](https://issues.apache.org/jira/browse/LOG4J2-696) bug, old as Log4j 2 itself. The attempted solution has no chance to work, since the `@PluginElement` annotation only accepts [classes annotated with `@Plugin`](https://logging.apache.org/log4j/2.x/manual/plugins.html) and `String` is final.
   
   Since you can embed pattern flags in the regex (e.g. `(?i)` instead of `CASE_SENSITIVE`), I believe that we can just remove the annotation on the parameter.
