=== What prefix to use? ===
There are various ways to tag toilets in OpenStreetMap:
- The toilet is added as standalone node or way using {{Tag|amenity|toilets}}
- The toilet is added as part of another amenity, using {{Tag|toilets|yes}}. For example {{Tag|amenity|restaurant}} with {{Tag|toilets|yes}} indicates that there is a toilet at the restaurant which (at least) customers are allowed to use. In this case, all tags describing the toilet(s) should be prefixed with the prefix{{Key|toilets:*}}.
Furthermore, some tags will _always_ use a toilets-prefix, for example {{Key|toilets:paper_supplied}}. For a full overview of those tags, please refer to {{Tag|amenity|toilets}}
The toilets-tag does not indicate how much toilets there are at a given location. There might be just one or multiple toilets. They can be split into different parts, each designated to certain groups of people. In Western countries, there are typically toilets for women, men and a designated toilet for wheelchair users (disregarding gender). If there is a toilet designated for wheelchair users, the prefix {{Key|wheelchair:*}} is used to add properties about this wheelchair accessible toilet. If there is but a single toilet and this toilet might be wheelchair accessible (and typically also used by non-wheelchair-users), the properties do not need prefix.
It is still useful to map properties about wheelchair accessibility, even though the toilet is not explicitly marked as "wheelchair-accessible". For example, a toilet might be built in an attempt to be wheelchair-accessible, but might have failed to meet the legal requirements. As such, the toilet cannot be (legally) advertised as wheelchair-accessible; but might have some facilities making it available to some wheelchair users.
