- * Validates the HTML attribute ID.
- * @warning Even though this is the id processor, it
- *          will ignore the directive Attr:IDBlacklist, since it will only
- *          go according to the ID accumulator. Since the accumulator is
- *          automatically generated, it will have already absorbed the
- *          blacklist. If you're hacking around, make sure you use load()!
