A modest proposal for VOEvent

[Petr Kubánek]

Then the question is: who will validate it and how you will enforce that
people will not invent their own names.

Honestly, I would like to see for EQU something that is possible to
validate against schema for missing attributes. XML parser will also
creates for me a structure I can use, not a mess I have to figure out
what it means.
