It is unclear what standard was initially applied here, #1304 (comment) talks about five categories but the portal currently only lists four and both CMAS/WEA and EU-Alert use at least six relevant categories that are handled on todays mobile devices:

  1. Presidential wide alerts, corresponds to EU-ALERT level 1
  2. Extreme threat, corresponds to EU-ALERT level 2
  3. Severe threat, corresponds to EU-ALERT level 3
  4. Public safety, corresponds to EU-ALERT level 4 (former EU-Info)
  5. Child Abduction Emergency (Amber Alert), corresponds to EU-Amber
    Message
  6. Test alerts

There are several kinds of test alerts and the different channels used to send cell broadcast messages also vary in the certainty that a user is affected by an event but I think we won't get closer than that for notification categories, and everything else should be left to a specific portal, see #1304 (comment)

EDIT: note that on most handests the 1. category can't be disabled in the UI, maybe that's why it didn't get added initially?

Reference is 3GPP TS23.041.

The DBus protocol specifies it with a `-`.

Adding the two missing categories seams reasonable. Also, good catch on the missing dash.

+1 from me.
