Here is an image of a "Schutzstreifen":

So is that the same marking as a shared_lane?

The cyclemap and velomap interpret cycleway=lane as the bicycle have
to move on that lane. So its mandatory. But with the new tagging the
useage is stated by cycleway:bicycle=designated|yes. And it is only
implicit documented on the wiki. I will fix that if we come to a
conclusion on this thread.

Hm, so should it be deleted from the wiki-page?
