  match /databases/{database}/documents {
    match /myCollection/{document} {
      function mySchema() {
        return request.resource.data.keys().hasAll(['name'])
          && request.resource.data.name is string
          && request.resource.data.optionalProp is string;
      }

      allow read: if request.auth != null;
      allow create, update: …
