[bv-dev] Cleaning up Java EE spec and move BV specifics to the BV spec (was Re: Support DI within constraint validators)

[Emmanuel Bernard]

Hey Linda,

What do you think about that in principle?
We were discussing whether or not BV should describe what CDI integration it has, Gunnar found out that some integration descriptions are in the Java EE umbrella spec.
It made sense at the time but we are thinking now that we should bring back that kind of information "in-house" and have a Java EE integration chapter inside the BV spec.

That would mean that we need to remove part of section EE 6.27 and probably point to the BV chapter instead. Does that make sense to you? It seems to be the way of things in the EE sphere these days and centralizing the info for a given technology seem to make sense.
