2) Encapsulation and Distribution of one or more emergency messages  
or alerts or notifications

A Radiological sensor triggered at a prominent Tunnel toll booth.  
Radiation alarm levels indicates possible dirty bomb.

Authorities decide to send multiple messages to a number of  
jurisdictions. They send an EDXL Distribution Element with two  
encapsulated CAP messages and a GIS shapefile describing the affected  
area. The first CAP message notifies the area where the sensor has  
been triggered. The second CAP message is an alert to emergency  
response agencies that the state EOC has been activated, and requests  
the agencies to be on alert.  The shapefile provides local geospatial  
detail for use in recipients' modeling applications.
