We have several inconsistencies:

• Bridge-related annotations are in the org.hibernate.search.mapper.pojo.bridge.declaration package, close to all other bridge-related APIs
• ... except IdentifierBridgeRef and ValueBridgeRef, which are in the org.hibernate.search.mapper.pojo.mapping.definition.annotation package
• ContainerExtraction and ContainerExtract are in the org.hibernate.search.mapper.pojo.mapping.definition.annotation package, even though most other APIs related to container extractors are in the org.hibernate.search.mapper.pojo.extractor package.
• and so on.

We should decide on a single strategy and apply it for everything:

• either annotations are in an annotation sub-package under the package that hosts related APIs
• or all annotations of the POJO module are in a single package.
