[Tagging] Self explanatory?

[Martin Vonwald]

Hi all,

I was thinking about a problem that affects renderers and navigational
devices in more or less the same way. I came up with a solution and
would like to know if it is understandable. I mapped four areas with
currently used tagging styles and added my solution. I would like to
ask you to have a look at the following images and tell me if you
understand what's going on. Please don't comment on the underlying
tagging styles - I randomly selected some I know (and may or may not
support them).
