/**
 * A method to allow to invoke the parsing without accessing the LibLoader layer. The data to be parsed is held in the
 * given InputSource object./*from  w w  w  . ja va 2  s.c  o m*/
 *
 * @param manager    the resource manager used for all resource loading.
 * @param input      the raw-data given as SAX-InputSource.
 * @param context    the resource context used to resolve relative resource paths.
 * @param parameters the parse parameters.
 * @return the parsed result, never null.
 * @throws ResourceCreationException    if the resource could not be parsed due to syntaxctial or logical errors in
 *                                      the data.
 * @throws ResourceLoadingException     if the resource could not be accessed from the physical storage.
 * @throws ResourceKeyCreationException if creating the context key failed.
