	// Certificates describes a set of certificates that the PeerConnection
	// uses to authenticate. Valid values for this parameter are created
	// through calls to the GenerateCertificate function. Although any given
	// DTLS connection will use only one certificate, this attribute allows the
	// caller to provide multiple certificates that support different
	// algorithms. The final certificate will be selected based on the DTLS
	// handshake, which establishes which certificates are allowed. The
	// PeerConnection implementation selects which of the certificates is
	// used for a given connection; how certificates are selected is outside
	// the scope of this specification. If this value is absent, then a default
	// set of certificates is generated for each PeerConnection instance.
