VMAP-1.0-root-version-value
`<VMAP>` version attribute should be `"1.0"` — the only published VMAP version
WarningVMAPIAB VMAP 1.0.1 §2.3VMAP 1.0 (all VMAP documents)
Short answer
The only published version of the VMAP specification is 1.0. Any other value is unrecognised and may cause players to reject or misparse the document.
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. VMAP rules validate the ad break schedule envelope. Malformed break timing, wrong namespace declarations, or invalid AdSource content prevent players from resolving any of the ads in the playlist. Affected scope: VMAP 1.0 (all VMAP documents).
