Why not consider all leaving exception messages as strings.
Any more complex information can be encoded in the string as an
XML message. That message can then be sent by well defined
mechanisms from one subprogram to another, one task to another,
and across distributed systems.

Many systems are currently migrating towards using XML encoding
for inter-process and inter-processor communication. Why not 
provide an Ada built-in mechanism to produce and consume 
exception information as streams of XML messages?
