DRY Documentation and Nested Routes

[Josh]

I have some routes for show like so:

1. /foo/{foo_id}/bar/{id}.json
2. /foo/{id}.json

I'm trying to DRY up my documentation.

Can I somehow specify path variables (especially when nested) while also DRYing up my documentation? For example, for the two paths above, could I have a single show documented in a base class that would handle both (and other similar) cases?
