VMAP-1.0-adbreak-repeatafter-format
`<AdBreak>` repeatAfter does not match the required hh:mm:ss[.mmm] format
WarningVMAPIAB VMAP 1.0.1 §2.3.1VMAP 1.0 (all VMAP documents)
Short answer
When repeatAfter is present on <AdBreak>, its value must be a timecode in hh:mm:ss or hh:mm:ss.mmm format. A malformed value will be ignored, effectively disabling repeat breaks.
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).
