      1. What would you like to communicate to the user about this feature?
      2. Would you like the user to see examples of the syntax and/or executable code and its output?
      3. Which versions of the driver/connector does this apply to?

      Motivation: JAVA-3677 Introduced the use of BsonRepresentation annotation in order to have clean PoJo. That was a nice improvement.

      The current annotation cannot be used however in List & Maps: i.e. is not possible to have something like this:

       

      List<@BsonRepresentation(BsonType.OBJECT_ID) String>  
Map<@BsonRepresentation(BsonType.OBJECT_ID) String, MyPojo>

       

       

      This is mainly because the current annotation target is the following 

       

      @Target({FIELD,METHOD})

       

      It would be nice to have also as target TYPE_USE (e.g. thishttps://javaee.github.io/javaee-spec/javadocs/index.html?javax/validation/constraints/package-summary.html annotation can be used in type arguments of List and Map.

       

      In the C# driver this support is available: we have the DictionaryRepresentationhttps://mongodb.github.io/mongo-csharp-driver/1.11/serialization/ annotation
