Access to all persons regardless of sex or gender
Denotes that access is unrestricted by a person's sex or gender. This is an access tag following the same rules as those described in access=*, though the presence of this tag with a "yes" value necessarily implies a "yes" for all other gender-based access tags.
It's probably best to express this type of access as unisex=yes and let the implications take care of other sexes/genders since the number is not guaranteed to be exactly two across all cultures. It's also faster to tag in this way.
A value of "yes" implies "yes" for all other gender-based access tags, but this can be overridden by adding more access role tags. In case of conflict, resolve in favour of more access.
