 1. The `Config` implementation detects whether the type of a retrieved configuration value is a composed configuration.
 This is handled equally, whether the configuration is retrieved programmatically, or via dependency injection.
-The configuration value type is considered a composed type if
-  - the type definition is annotated with the `@ComposedConfig` qualifier
-  - the dependency injection defines the `@ComposedConfig` qualifier
-  - the configuration value is access via the `ConfigAccessor` API and it's dedicated `composed()` method
+The configuration value type is considered a composed type if the type definition is annotated with `@ComposedConfig`.
 
 2. The retrieval of a composed value MUST be performed by a single config source at a time, in order of their defined priority.
 Due to the potential hierarchical nature of composed configuration, the individual sources must define coherent configuration compositions.

+=== Decisions & Considerations (for EG members, to be removed)
+- No prefix attribute added on `@ComposedConfig`, since it arguable doesn't provide much benefits. The injection point has to specify some property name anyway. Discussed on 2018-09-06.
+- Starting with supporting to annotate `@ComposedConfig` on types only, i.e. no qualifier and no annotation on the injection point. Discussed on 2018-09-06.
+- The programmatic `ConfigAccessor` API doesn't require a specific method (such as `composed()`), since the resolution currently requires the composed type to be annotated with `@ComposedConfig`.
