support sidewalk in default preset

[Klumbumbus]

While displaying sidewalk=* (​wiki) in the MapView would result in too much clutter (see also #10057) I think adding it to the highway presets would be fine. Any opinions?

[Don-vip]

Sounds fine.

In 7707/josm:

fix #10716 - add 'sidewalk' to appropriate highway presets; add validator warning for sidewalk=*on nodes and sidewalk=yes.

The value with highest number in use is none which follows a long the deprecated footway=both/left/right/none. Not sure if it wise to through a warning about it.

Do we need the values_context="sidewalk" ?

Replying to skyper:

Do we need the values_context="sidewalk" ?

I thought "both" is maybe translated to german with "beide" or "beidseits" or similar depending on the context. "beide" would not fit well for sidewalk. However beside sidewalk "both" is used only for overtaking in the presets and in german it is also translated with "beidseits" there. So we could remove values_context. However I'm not sure about other languages.

see #10716 - remove values_context="sidewalk", seems unnecessary

Are you sure the context is unneeded? This will join all translations of the same strings. For some languages this may not be right.

I also vote for keeping the context, it is important and the translation here will be different than other places using left,right,both .

[Klumbumbus]

Then we should also add the context for overtaking!?

[aceman]

Yes, you would make me happy :)

In 7709/josm:

fix #10716 - add values_context="sidewalk" and values_context="overtaking" in default preset for more precise translations
