It's important to mention that ExtVal provides several approaches to extend, customize,... the default behavior.
We recommend to choose one approach you prefer and use it consistently!
Basically there are 3 available approaches: Conventions (customizable if needed), ExtVal Java API, configuration via web.xml
So choose the approach you prefer! ExtVal tries to provide always a very simple approach for your custom implementations. If you can't find a simple one, just ask for support.
