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 to override ExtVal's defaults: 
- *Conventions*: just create extra Java classes or resource bundle's, give them a name according to the convention, and place them in the right package. ExtVal will find your customizations and use them.
- *ExtVal Java API*: if you'd rather use your own naming scheme and package structure, use ExtVal's Java API to make ExtVal aware of your customizations.
- Configuration via *web.xml*: use web.xml settings as another alternative way to let ExtVal know about your customizations.

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.

To get started, please read the [module overview and setup|EXTVAL:Module Overview] first.

h2. Validation Modules

The validation modules provide implementations for using different types of metadata immediately. In many cases one validation module might be enough for a project, but the modules can also be combined without problems.
