Every tag is for the renderer, otherwise all maps would be black lines

The tag 'layer' is purely to aid renderings.
That's not true. It represents things being above and below each other,
And is used solely by renders to distinguish what you said. However
'Layer' provides no real world interpretation of height distance
between objects.
It does not provide height, but it provides ordering.
...for the renderer. Who else do you think uses this data
Which is still
real world data, just less granularity.
In the case of tag saying what angle to draw something, that's a
specific drawing instruction, and I don't think it belongs.
Along with an angle, a position tag for the label would be useful to
avoid annoyances where it renders outside the perimeter of
irregular.shaped polygons.
So would saying that a particular object should be green. Once you add
specific drawing instructions, I don't see how to draw the line.

but that doesn't make it compulsory. These meta tags are a *aid* or
suggestion.
Can this really not be computed by renderers? It just seems like an
optimization problem.
