I fully agree -- I think that data format schemas (W3C/XML Schema)
are both too low-level and too format-specific to be a good solution.
Regarding JAXB and JAX-RS: I think validation is an orthogonal (if
related) concern, and thus ideally JAXB (data binding) nor JAX-RS
(rest-style web service framework) would play nicely with Bean
Validation API, and not try to solve this only for their respective
use cases.
Bean Validation API has bit limited scope, but it is an on-going
effort so there may be still time to effect what it will do, and how
well RI works.
I have so far used it for simple cases (min/max values, min/max
length, not null), for which it works quite well.
