Init.Class reads from config.xml and register KeyInfoHandler to _contentHandlerHash. However, as I known, no class calls getKeyInfoContentHandler so I think that this registeration process is not necessary. If I were right, a developer should actually do for extends and customize library is developing his own KeyResolvers and StorageResolvers which both are extends SPI.
Is it true? If this were true, please, remove registereation process in order to prevent misunderstanding.
