I've nothing special in mind. By pluggable I mean a way to override the
discovery mechanism like it's done with the ValidationProviderResolver. The
way used to specify the ConstraintValidator implementations will remain the
same.

Because I'm not sure it's possible to have a mechanism which works in a
modular and non-modular world out of the box. For example, to make it work
with OSGi you'll have to be depend on the API. AFAIK, JBoss Modules allows
to import/export service resources.
