Annotation that can be used to define name of root element used
for the root-level object when serialized, which normally uses
name of the type (class). It is similar to JAXB XmlRootElement and basically an alias for standard Jackson annotation JsonRootName (which you should usually use instead). 

Note that annotation has no effect on non-root elements: regular property
values and so on; their name is derived from getter/setter/field, not
from type itself.

 NOTE! Since 2.4 this annotation is usually not necessary and you should use JsonRootName instead. About the only expected usage may be to have different root name for XML content than other formats.
