Hi all, I'm in the process of integrating the method validation proposal into to the first draft of the spec. document. Thanks again for all comments and feedback. While going over the ParameterNameProvider interface I wondered where this interface should actually live. Should it be javax.validation.ParameterNameProvider or javax.validation.spi.ParameterNameProvider? Or put more generally, what's the intention of the spi package in the BV API? ParameterNameProvider is intended to be implemented by BV providers, integrators and clients. According to my understanding of the SPI idea (separate parts intended to be *implemented* by clients [SPI] from parts intended to be *used* by clients [API]) therefore I'd say it's a candidate for the SPI package. But following that reasoning, for instance also the ConstraintValidator interface should be part of the spi package, which it isn't in BV 1.0. Based on the contained classes I'm supposing that the BV spi package has a much more focused scope (bootstrapping). Then ParameterNameProvider should go into javax.validation. Any thoughts? Btw. there isn't much package-level JavaDoc for the BV API in general (only for javax.validation.groups). I think we should add some more for BV 1.1. WDYT? --Gunnar
