I'm well aware of route relations, of all types, but what have these
to do with 'destination:ref*' tags on /ways/?<br>
<br>
How does routing software, which "lacks support for the 'role' tag"
of route relations "cause problems for any editor, QA tool, or data
consumer"? It makes no logical sense. (quotes from Minh's original
post)<br></div></blockquote><div><br></div><div>We're just trying to determine if there is a reasonable use case for the link role in a road route relation.

<br></blockquote><div><br></div><div>Mappers are following this documentation and including on/off ramps in route relations with role=link. In most cases, an on ramp leading to a numbered route is generally not considered part of that route. To indicate which route it leads to, they way gets tagged with destination:ref. So also including it in the route relation with the link role doesn't seem to add any information. Given this we're thinking it makes sense to remove this suggestion from the wiki.<br><br><br></div></div></div></div>
