A modest proposal for VOEvent

[Rob Seaman]

Me again,

The registry and the schema will permit validating each packet  
autonomously.  Presumably some packets will fail.  If so, an app/ 
client/aggregator/subscriber is free to reject them.  The publisher  
then can fix the packet stream, or their registry entry for that  
stream, or lobby to change the schema.
