This error cause MAY be included in ABORT chunks that are sent
because an SCTP endpoint detects a protocol violation of the peer
that is not covered by the error causes described in Section 3.3.10.1
to Section 3.3.10.12. An implementation MAY provide additional
information specifying what kind of protocol violation has been
detected.
