 * matches if the value of the {@code management.logging.export.enabled} property is
 * {@code true} or if it is not configured. If the {@link #value() logging exporter name}
 * is set, the {@code management.logging.export.<name>.enabled} property can be used to
 * control the behavior for the specific logging exporter. In that case, the
 * exporter-specific property takes precedence over the global property.
