[bv-dev] OverridesAttribute questions

I have a couple of questions about @OverridesAttribute: 1. The spec says that #name() defaults to the name of the annotated attribute, but there is actually no default value declared. Should(n't) we declare as ""? 2. I don't have a clear understanding from the spec what the expectations are if there is a single override specified using the default constraintIndex value, but with multiple composing constraints of the specified type. Does the override apply to all? Is it an error? Matt
