You should turn parser into something more like a MetadataProvider. 
I removed the getValidators() method from parser and moved it to ValidatorImpl. The parser should not be aware of ValidatorImpl, nor Validator for that matter.

The MetadataProvider will be an interface anybody can implement. We will do the annotation version as well as the XML version (and probably some kind of XML overriding annotation version) but one can imagine a Script / Groovy DSLed version, a Programmatic API version and so on.

I imagine a MetadataProvider instance can be passed during the building phase to the ValidatorFactory. The same instance would then be shared for all Validators (kind of make sense, you can't parse XML for every single ValdiatorImpl instantiation).

That woul mean the parser ode needs ot be reworked to be immutable (at least work in concurrent calls)
