* Marker annotation that can be used to define a logical "any setter" mutator --
* either using non-static
* two-argument method (first argument name of property, second value
* to set) or a field (of type {@link java.util.Map} or POJO) -
* to be used as a "fallback" handler
* for all otherwise unrecognized properties found from JSON content.
* It is similar to {@code javax.xml.bind.annotation.XmlAnyElement}
* in behavior; and can only be used to denote a single property
* per type.
*
* If used, all otherwise unmapped key-value pairs from JSON Object values
* are added using mutator.
*
* NOTE: ability to annotated fields was added in version 2.8; earlier only
* methods could be annotated.
