invalid warning "crossing ways" for ways with different "level"

[RicoZ]

ways (such as highway=footway) in a building marked with level, see attached file.

Adding layer to avoid the warning seems not a good idea.

house with two ways on different levels

What is the algorithm determining whether to check "level" or "layer"? Is "indoor=yes" consulted?
What if there are both keys?

reading from the sourcecode:

• first check if layer keys are different, if so not crossing
• next the check if level keys are different, not crossing
• indoor not consulted - and would not make sense. You can have a walkway on a terrace:)

Looking at the source code I am thinking the test could be more relaxed and assume implicit street level as level=0. I wanted to make underground shopping malls and passages mappable with mainly level. For this case with current version I have to set street level ways as level=0 explicitly.

I could also tag the whole underground building with layer=-1 alternatively.. not sure that makes sense because I also do not tend to tag normal buildings with layer=1.
