XMLObject | Base class for all XMLObjects. |
"Value Object" classes used for holding data used by the application. Classes which extend XMLObject are capable of marshaling and unmarshaling XML data.
By convention, all fields which represent XML attributes should be prefixed with "attr", and all fields which represent XML elements should be prefixed with "elem". In addition, collections of elements should be named according to the type of object they contain. For example, a list of PLConcepts should be named "elemPLConcept". This naming restriction will likely be removed in future releases.
