DAAST-1.0-wrapper-vast-adtaguri
`<VASTAdTagURI>` is a VAST element — DAAST wrappers redirect via `<DAASTAdTagURI>`
WarningDAASTIAB DAAST 1.0 §3.3.1.1DAAST 1.0 and 1.1 (all DAAST documents)
Short answer
Using <VASTAdTagURI> in a DAAST <Wrapper> is a common copy-paste error from VAST templates. DAAST wrappers must use <DAASTAdTagURI> to redirect to the next hop.
Why this matters in production
This rule is a strong risk signal. Tags with this issue often still parse, but they become brittle across SDKs, SSAI resolvers, and CTV environments. 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).
