31 * A rule that a protocol request and message must meet in order to be valid and secure.

82 * SecurityPolicyRule for replay detection and freshness checking.
84 * <p>A ReplayCache instance must be available from the runtime, unless

88 * <p>Messages must have been issued in the past, but no more than 60 seconds ago,

106 * Allows the message issuer to be authenticated using a non-XML digital signature
107 * over the message body. The transport layer is not considered.
