                    Contains a valid value when propertyType is SerializedPropertyType.ManagedReference. This property is Read Only (you cannot write to it). 
 
                    The full type name string returned has the following format: "[assembly-name] [namespace.][parent-class-names][classname]" where: 
                    - [assembly-name] is the name of the assembly that contains the target type 
                    - [namespace.] is an optional (if empty) namespace followed by a '.' 
                    - [parent-class-names] is a '/' separated list of optional parent class names (in the case of nested class definitions) 
                    - [classname] is the actual dynamic type name of the managed object class. 
 
                    'null' references return an empty type string.
