Hmm, but it does work.

I came up with something in the attached file. I would be very pleased 
if someone could have a look at it, and tell me if this is fragile code
or if there are any other pitfalls I don't see yet.

The code for the actual tagging is missing yet, but this could be made
along Volodyas proposal.

Thank you so much.
