* When annotating value classes, configuration is used for instances
* of the value class but can be overridden by more specific annotations
* (ones that attach to methods or fields).

* An example annotation would be:
*
* @JsonSerialize(using=MySerializer.class,
* as=MySubClass.class,
* typing=JsonSerialize.Typing.STATIC
* )
*
* (which would be redundant, since some properties block others:
* specifically, 'using' has precedence over 'as', which has precedence
