         * end of the whole document (!!!), because I can't add a message, unless
         * I already added it's parent messages, thread, forum and category.
         *
         * NOTE: In SetPropertiesRule (see attachment processing below), I had to
         * define setAttachmentId() instead of setAttachmentID(), to avoid some
         * strange problems that Digester has (because it tries to automatically
         * convert all words to first letter capital, other small, and it
         * doesn't handle well the case with "attachmentID" property, that is,
         * it doesn't "see" setAttachmentID() method).
