usc_all_unknown

urgency, severity, and certainty all reported as Unknown — using Unknown as a default across all three fields limits alert interpretability.

CAP's <urgency>, <severity> and <certainty> each default to "Unknown" when the sender doesn't set them. Any of them can legitimately be Unknown, but all three together suggests the alert is meaningless and unuseful. Displays that style or route alerts by these fields (e.g., set color by severity, or sort by urgency) have no information to work with.

Test messages should be as realisitic in form as possible in order to provide a genuine system test.
