    /*
     * IT WOULD MAKE NO SENSE TO ADD HERE EVENTS FOR CDATA AND/OR COMMENTS. The reason is that these inline
     * handlers are meant to pre-process inlined text during the template parsing phase, and as a result of their
     * processing text events might be broken into several. E.g. a "one  [['two']] three" will actually be broken
     * into two "one " and " three" text events, with a "[# th:text="'two'"/]" element in the middle.
     *
     * This is relatively harmless to pre- and post-processors expecting to act on entire text blocks, because they
     * are single classes and have always the possibility to merge consecutive blocks of text. But CDATA and comment
     * blocks have prefixes and suffixes ("", ""), so splitting these events into several
     * would provoke the insertion of prefixes that will actually break the syntax. That is why CDATAs and Comments
     * (inside which inlined output expressions ARE ALLOWED) will always be processed during the processor execution
     * phase.
