Missing some property exports - for example 'performer`

[davie-robertson]

I'm refactoring my code to use all the types defined in schema-dts for Events and I thought that I could apply the performer type to my existing objects, but there's no export of performer from schema-dts.

There's not much documentation to go on, and maybe this isn't the correct use-case for the library, but is this the expected approach?

import { Person, Organization, Thing } from 'schema-dts';

export type Performer = Person | Organization | Thing;

and then elsewhere in my code I use it like this:

@state() performer: Performer = { '@type': 'Person', name: this.user?.displayName || '' };

// When handling performer updates
private handlePerformerUpdate(performers: Performer[]) {
  this.eventData.performer = performers;
}
