Creative subtypes (audio and video) value 11 means VAST 4.1
VAST 4.1 inline documents, the version that brought audio into VAST. An AdCOM addition.
When to send it
Send 11 when the player handles VAST 4.1 inline documents. VAST 4.1 absorbed audio ads, replacing DAAST, and expanded support for verification and server-side insertion. The value is in the AdCOM list but not in OpenRTB 2.5, so older bidders may not recognize it.
Audio and CTV buyers commonly require 4.1 or later. Pair it with 12 if wrappers are accepted. It is confused with 7 (VAST 4.0) and with 13 (VAST 4.2); declare each version the player has been tested against.
