The AdditionalCriteria maps to EclipseLink's existing descriptor additionalJoinExpression. The AdditionalCriteriaGroup and Callback and naming and enabled options are new functionality. Some insight into their requirement, usage, design and implementation in the runtime would be useful.

The callback seems quite complex, and uses reflection. Some similar to our DescriptorCustomizer and SessionCustomizer may be simpler. We could have a QueryCustomizer interface that takes a DatabaseQuery before execution and allows the user to customizes it. Or the existing SessionEventListener could be used.
