/revisions/{id}/{revisionguid} - usage of this route is not clear to me.
can someone provide a working url and perhaps a simple use case.
If you call /revisions/{id} where {id} is a post id (question or answer) you'll get a list of revisions to that post. Each revision has a unique GUID that identifies it.
If you call /revisions/{id}/{guid} where {id} is a post id and {guid} is one of those revision GUIDs you'll get just that one revision.
{id} is technically vectorized in both cases, but obviously the latter will only ever return a single result.
