* https://w3c.github.io/webappsec-referrer-policy/
* ('no-referrer', 'no-referrer-when-downgrade', 'same-origin',
* 'origin', 'strict-origin', 'origin-when-cross-origin',
* Setting it to false prevents the meta tag from being output
* (which results in falling back to the Referrer-Policy header,
* or 'no-referrer-when-downgrade' if that's not set either.)
+ * Setting it to an array (supported since 1.31) will create a meta tag for
+ * each value, in the reverse of the order (meaning that the first array element
+ * will be the default and the others used as fallbacks for browsers which do not
+ * understand it).
