Does ways that are in relation inheriting properties from relation?
Example: there is a way with route=ferry tag, thats fine.
there is a way with no attributes but is a part of a relation with tags route=ferry and name=“blue road” is this valid data model, with ways that have same tags or every single way must have “same” attribute as relation?
When a Garmin map is created with mkgmap, tags from relations are added to the underlying ways, and then the way gets rendered. Hence it is not necessary for a way to have a tag at all when it is part of a relation.
