(My notation above is just to illustrate concepts; not supposed to be a binding.)\r\n\r\nNow:\r\n\r\n* Should I be able to broadcast two or more distinct events about the same data (`foo`) described by the one context (`contentType: text/plain ; extensions: ... etc.`)?\r\n* Can a [context definitionally describing \"circumstantial information about the Occurrence\"](https://github.com/cloudevents/spec/blob/master/spec.md#context) be conceptually shared between events?\r\n* Can one Occurrence appear in two events?  Must those two events' contexts be non-equal?"}}
