VMAP error tracking URI should include the `[ERROR_CODE]` macro

InfoVMAPIAB VMAP 1.0.1 §2.5VMAP 1.0 (all VMAP documents)

Short answer

VMAP error tracking URIs should include the [ERROR_CODE] macro so the player can substitute the actual error code when firing the beacon. Without it, error diagnostics carry no machine-readable code.

Why this matters in production

This rule is advisory rather than fatal, but it still matters for portability, debugging speed, and keeping tags predictable across different buyers and playback stacks. 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).
