------- Comment #4 from Stefan Kost (gstreamer, gtkdoc dev)  2008-01-10 15:40 UTC -------
We have 3 kind of tags:
1) known mapped ones
2) known unmapped ones or new (unmapped) ones

- type 1 is fine
- type 2 can be caught with the technique outlines in comment #3

So if we want to generate a chart as described in comment #1, we would need:
- some way to get all registered tags from gst/gsttaglist.c::__tags hashtable
  to build a dummy taglist
- get all tagsetter elements from registry and send the list to them
- get the unhandled tags back -> red
- those in the input list that or not in the unhandledlist -> green

the red one need to be rechecked from time to time, wheter they can be
supported.
