Hrm, this might even warrant a new (boolean) config option, which, if
set, will mark a data-set as "interesting" and thus causes a
notification to be dispatched if the value is missing. Of course, your
work-around works as well, but that should rather be considered a bad
hack (no offense ;-)) and it's fairly hard to understand when looking at
the config file.
Any other opinions about that?
