+==== Subscription Exceptions
+
+The `Publisher` for a subscription request may complete with an error signal in which case
+the underlying transport (e.g. WebSocket) sends a final "error" type message with a list
+of GraphQL errors.
+
+`DataFetcherExceptionResolver` cannot resolve errors from a subscription `Publisher`,
+since the data `DataFetcher` only creates the `Publisher` initially. After that, the
+transport subscribes to the `Publisher` that may then complete with an error.
+
+An application can register a `SubscriptionExceptionResolver` in order to resolve
+exceptions from a subscription `Publisher` in order to resolve those to GraphQL errors
+to send to the client.
