Creative subtypes (audio and video) value 7 means VAST 4.0
VAST 4.0 inline documents, added to the list in OpenRTB 2.4.
When to send it
Send 7 when the player parses VAST 4.0 inline documents. VAST 4.0 separated interactive code from the media file and added the universal ad ID and mezzanine files for server-side transcoding. OpenRTB 2.4 added this value along with its wrapper counterpart 8.
CTV and server-side insertion buyers often require 4.x so they can supply mezzanine files and ad IDs. It is confused with 11, 13, and 15: because the later 4.x versions were added after DAAST, their numbers do not follow 8. A player that handles VAST 4.2 should list 7, 11, and 13, plus the wrapper values it accepts, rather than assuming one implies the others.
