You need a '&' between type=route and route=bus, did you have one or is
just a typo in the example?

O.k. I've added the & and now it parses without complaining, but I think it does nothing. I tried to highlight the Donauradwanderweg which is tagged as route=bicycle but it did not work.
The best solution for relations would actually be to do them via an overlay so one doesn't loose the properties of the underlying way!

Yes looks like a bug, should be fixed now.  Thanks

Not completely, but it's working under the condition:
Lines 1-4
1: 0x140: 0x11, 0x0e
2: 0x141: 0x2a, 0x0e
3: 0x142: 0x10, 0x0e
4: (empty but existing)

Is working.

1: 0x140: 0x11, 0x0e
2: 0x141: 0x2a, 0x0e
3: 0x142: 0x10, 0x0e

and line 4 not existing brings up the following error:
Error in style: Error: (overlays:3): List of numbers expected
Could not open style null

So for the moment one has to create an empty line 4 by exiting line 3 with enter (and thereby creating an empty line 4).



Nevertheless I would prefer to have the overlay function independent of the underlying way, would this be possible (whereas 0x0e stands for bicycle=yes)?

Status Quo:
<<<Lines>>>
highway=path & bicycle=yes [0x140 resolution 16]
highway=footway & bicycle=yes [0x141 resolution 16]
highway=track & bicycle=yes [0x142 resolution 16]
<<<Overlay>>>
1: 0x140: 0x11, 0x0e
2: 0x141: 0x2a, 0x0e
3: 0x142: 0x10, 0x0e
4: (empty but existing)

I wish overlays would work as simple as in this example:
<<<Lines>>>
bicycle=yes [0x140 resolution 16]
<<<Overlay>>>
1: 0x140: 0x0e

The advantage of this scheme is, that one does not need to know what other tags are applied to the object. This is especially important if you search for several different tags that all could be used on one way. i.e. highway=track oneway=yes, bicycle=yes, tracktype=grade2 and one does not need to specify all possible combinations!
