Requests left in the most constrained policy window that applies to this request.
On 429, seconds until the most constrained policy frees up; it equals Retry-After there. On a successful response it reports the length of that policy's window rather than the time left in the current one, so treat it as the window size, not as a countdown — the counter to pace against is RateLimit-Remaining.
Most constrained policy applied to the request, as <limit>;w=<window in seconds>.
Version tag of the returned resource. Send it back in If-Match on the next PATCH or DELETE.
