com.sun.syndication.feed.synd.SyndCategoryListFacade
class SyndCategoryListFacade
List implementation for SyndCategoryImpl elements. To be directly used by the SyndFeedImpl and SyndEntryImpl classes only.
It acts as a facade on top of the DCSubjectImpl elements of the underlying list and remains in synch with it. It is possible to work on either list, the categories one or the subjects one and they remain in synch.
This is necessary because the SyndFeedImpl categories are just a convenience to access the DublinCore subjects.
All this mess to avoid making DCSubjectImpl implement SyndCategory (which it would be odd).
