DAAST-1.0-root-version
Root `<DAAST>` element must have a version attribute
ErrorDAASTIAB DAAST 1.0 §3.1.1DAAST 1.0 and 1.1 (all DAAST documents)
Short answer
The <DAAST> root element must carry a version attribute. Without it, players cannot determine which version of the spec applies and will typically discard the response.
Why this matters in production
This rule is usually a delivery blocker. Many players, SDKs, and ad servers will discard the response or skip the affected creative once this condition is hit. DAAST rules validate the structural and semantic requirements specific to digital audio ad serving. Audio-specific fields like Category, AdInteractions, and audio MediaFile attributes are required by the spec and are absent from standard VAST validation. Affected scope: DAAST 1.0 and 1.1 (all DAAST documents).
