add quest toilets:wheelchair for object with toilets=yes

[ViolaineDo]

I am suggesting here a quest about wheelchair accessibility for toilets in an amenity. This could be disabled by default as you would need to enter the facility. This would filter object with tags : toilets=yes or toilets:access=customers or permissive or yes.
Defining if a toilet is wheelchair accessible or limited or not would be as for amenity=toilets (though instead of having as a result wheelchair=yes/no/limited we would have toilets:wheelchair=yes/no/limited)
This is an important information to know for people with disabilities in order for them to find their best restaurant / bar to go.
What are your thoughts?

QUEST PROPOSAL (UPDATE)

General

Affected tag(s) to be modified/added: toilets:wheelchair
Question asked: Is this toilet accessible for wheelchair ?
Answers:

• Yes means doorway’s inner width are large enough (min. 90 cm), space is large enough (150 x 150 cm), wheelchair-height toilet seat, folding grab rails, accessible hand basin, doorway is openable (not to heavy), no steps
• No means toilets is not accessible at all : steps, door is too heavy or not large enough
• Limited means : you can access the toilet : door is large enough, no steps, door is openable but the services are limited (for ie their is no grab rails)

References :

• toilets:wheelchair
• wheelchair

Checklist

Checklist for quest suggestions (see guidelines):

• 🚧 To be added tag is established and has a useful purpose
• 🤔 Any answer the user can give must have an equivalent tagging (Quest should not reappear to other users when solved by one)
• 🐿️ Easily answerable by everyone from the outside but a survey is necessary
• 💤 Not an overwhelming percentage of elements have the same answer (No spam)
• 🕓 Applies to a reasonable number of elements (Worth the effort)

Remarks:

• Tag is more or less established in regard to the 2 references I put, and taginfo. Issue is that limited option is not explicitely set on wiki key:toilets:wheelchair but is on wiki key:wheelchair. Nevertheless the subtag system (wheelchair=*) has this "limited" option. I assume that the wiki for toilets:wheelchair is not up to date and would integer a limited option. Still this tag, "limited" is used (1000 times, see taginfo link)
• One would need to enter the amenity to fill in this quest, so as for similar quest, I would disable it by default.

Ideas for implementation

Element selection: toilets=yes or toilets:access=customers or permissive or yes.

Sorry I wasn't sure if it needed to be discussed first, done now

Thanks for filling it out.
FYI: The template is exactly the thing you need to fill out in order for it to be discussed. 😄

Now some remarks about the general idea:

• Why did not you tick "To be added tag is established and has a useful purpose"? As far as I see it, it fits both these criterias. Anything that speaks against it?
• The problem I see is the "difficult"/extensive criteria you indicated in your answers. These are quite a lot… this is hard to explain/convey in a small space/quest that we have when asking a quest.
  I know [it's possibly an issue of the tag, because the wiki lists this criteria, too]https://wiki.openstreetmap.org/wiki/Key:toilets:wheelchair#Usage).
• You mentioned the result "Limited". However this is not listed in the wiki. Wiki has only yes or no… 🤔
  There is a quite old and unanswered discussion about that, but nobody replied…

Just because of the issue of the limited tag you also pointed out. I explained my view in my remarks.. "Tag is more or less established in regard to the 2 references I put, and taginfo. Issue is that limited option is not explicitely set on wiki key:toilets:wheelchair but is on wiki key:wheelchair. Nevertheless the subtag system (wheelchair=*) has this "limited" option.

I would think not many would have seen this.. I do think that the wiki is not up to date on some places and that we need to play with taginfo, and crossreference different wikipages... Here a subtag doesn't take all the possible values of the initial tag (wheelchair) which is for me a problem... I am ready to launch a discussion on osm mailing list though if you think it would be necessary...

One more input about this value limited : it is integrated in the wiki page about toilets (so i think it can be used): https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dtoilets#Toilets_within_places

Sounds reasonable, however, being disabled by default, this'd have quite a low priority to implement.
