Hey Roy,

This looks good to me.

If this statement were intended to be, say, part of a standards document--that is, where we might quibble about precision, I would point out that technically the bit following # is not part of a VO identifier. More precise wording would be...

 "...will often contain identifiers that build on the IVOA standard  identifier, defined and discussed in [16]. The packet identifiers take  the general form "ivo://authorityID/resourceID#localID",..."

However, if this is part of most any other document, it's probably not worth clouding the issue over such a detail, so it's fine as is.

This is an intriguing idea. This would imply that you would be able to use the registry interface to resolve, harvest, and/or search for events. All this is possible in principle (though you would have to support a VOEvent format that is based on VOResource).

In practice though, we probably wouldn't integrate VOEvent records into our full registries, as these would clearly be too fine grained. So I'm not sure how useful this would be.
