VOEvent, unique id's, and IVORNs

[Tony Linde]

Hi Matthew,

That was my suggestion - you could register the publishers as Organisations
in the meantime but with throw-away resource IDs. It'd be safer than
ostensibly using AuthIDs as publisher IDs.

Key part of Al's message is to split the event id from the publisher with
'#' rather than '/'.

Cheers,
Tony.
