⚠️ content.usc_divergent_between_infos — all <info> elements within a single <alert> should have the same <urgency>, <severity> and <certainty> values, so the alert can be processed consistently as a unit; messages with different U/S/C values should be sent in separate <alert> bodies. |
⚠️ content.multiple_categories — an <info> block declares more than one <category> (Met + Health) — CAP allows it, but a receiver that routes or files by category must choose one, and different receivers choose differently. [source: Art, 2026-08-02] |
⚠️ content.no_instruction_time — instruction does not say by when the protective action should be taken — no deadline and no immediately-class directive. |
