How to terminate MFA flow with an error?

"MyEvent". "authn/Whatever" is an actual event name, it just happens to use a convention to recognize that it's a flow ID and there are special rules in the flows for doing things in response to those strings:

        <transition on="#{currentEvent.id.startsWith('authn/')}" to="ReselectFlow">
