Creative subtypes (audio and video) value 13 means VAST 4.2
VAST 4.2 inline documents. An AdCOM addition.
When to send it
Send 13 when the player parses VAST 4.2 inline documents. Like the other later 4.x values, it lives in the AdCOM list and not in the OpenRTB 2.5 document.
Buyers that build creative to the 4.2 schema look for 13 and fall back to 11 or 7 when it is missing. A player that lists 13 but drops 11 and 7 may lose bids it could have rendered, since later 4.x players are generally able to read earlier 4.x documents. It is confused with 14 (its wrapper) and with 15 (VAST 4.3).
