+| `reward` | OPTIONAL | `0` (no) \| `1` (yes). The user receives a reward for viewing the ad | `Placement.reward`, `imp.rwdd` |
+| `instl` | OPTIONAL | `0` (no) \| `1` (yes). The ad is interstitial or full screen | `DisplayPlacement.instl`, `imp.instl` |
+| `plcmt` | REQUIRED for video ads (`channel` `video`, or video on `channel` `ctv`); otherwise OPTIONAL | One value from List: Plcmt Subtypes - Video: Instream (1), Accompanying Content (2), Interstitial (3), No Content/Standalone (4), Pause (5), Screensaver (6), Overlay (7), Squeezeback (8), In-scene (9) | `VideoPlacement.ptype`, `video.plcmt` |
+| `skip` | OPTIONAL | Video or audio. `0` (no) \| `1` (yes). The placement lets the user skip the ad | `VideoPlacement.skip`, `AudioPlacement.skip`, `video.skip` |
+| `skipafter` | OPTIONAL | When `skip` is `1`: seconds the ad plays before the placement enables skipping | `VideoPlacement.skipafter`, `AudioPlacement.skipafter`, `video.skipafter` |
+| `playmethod[]` | OPTIONAL | Video or audio. Values from List: Playback Methods in use, such as Initiates without any specific user interaction with Sound On (1), Initiates without any specific user interaction Sound Off by Default (2), Initiates on Click with Sound On (3) and Continuous Playback (7) | `VideoPlacement.playmethod`, `AudioPlacement.playmethod`, `video.playbackmethod` |
+| `api[]` | OPTIONAL | Values from List: API Frameworks that every impression supports, such as MRAID 3.0 (6), OMID 1.0 (7) and SIMID 1.1 (9) | `DisplayPlacement.api`, `VideoPlacement.api`, `AudioPlacement.api`, `banner.api`, `video.api`, `audio.api` |
+| `refresh` | OPTIONAL | `{ min_interval_s }`: minimum seconds a creative renders before the slot refreshes | OpenRTB 2.6 only: `imp.refresh.refsettings[].minint` |
+
+`plcmt` takes its OpenRTB 2.6 name. AdCOM 1.0 carries the same list as
+`VideoPlacement.ptype`. OpenRTB 2.6 `Audio` has no `skip`, `skipafter` or
+`playbackmethod`, so for audio those keys map to AdCOM 1.0 `AudioPlacement`
+only.
+
+- A key that is present holds for every impression of the line item. An absent
+  key does not constrain it: a line item that omits `instl` can deliver to
+  interstitial and non-interstitial impressions alike. AdCOM 1.0 reads an
+  absent `reward` or `instl` as `0`; here it means either value.
+- The seller MUST NOT deliver the line item to an impression that does not
+  match a key that is present. An impression matches `api[]` when it supports
+  every listed framework, `playmethod[]` when its playback method is one of the
+  listed values, and `refresh` when the slot renders each creative for at least
+  `min_interval_s` seconds before it refreshes, or does not refresh. It matches
+  any other key when its value is equal.
+- Unless `api[]` includes OMID 1.0 (7), a line item whose `committed_metrics[]`
+  includes `viewable_rate` and whose `environments.available[]` includes
+  `app_mobile` or `ctv` SHOULD NOT offer a `measurement_source` vendor other
+  than the seller.
