* Root bean definitions are the most common type of bean definition.

* class plus optionally constructor argument values and property values.
*
* Note that root bean definitions do not have to specify a bean class:
* This can be useful for deriving childs from such definitions, each with
* its own bean class but inheriting common property values and other settings.
