I have a tree of game entities composed of components. I want to save/load everything to xml file, where my saving/loading code must be located:

  1. Scene class containing root node and functions save/load
  2. Utility class containing static functions taking root node as argument
  3. Member function inside entity class (not preferred cause of 3rd party xml lib)

Is it necessary to have scene class? Maybe some other item management architecture is better.
