Because, the @Input annotation can let you inject the whole representation
as a method parameter for example, instead of only particular metadata. But,
I think that we also need the specific metadata annotations: @MediaType,
@CharacterSet, @Encoding, etc.

No, on the entity class, we should only allow the usage of the
@Representation annotation (in addition to the metadata annotation) as it
could be used for both input and output purpose.
