+/**
+ * FeaturePolicy
+ * ~~~~~~~~~~~~~
+ *
+ * Each document and each HTMLIFrameElement have a FeaturePolicy object which is
+ * used to allow or deny features in their contexts.
+ *
+ * FeaturePolicy is composed by a set of directives configured by the
+ * 'Feature-Policy' HTTP Header and the 'allow' attribute in HTMLIFrameElements.
+ * Both header and attribute are parsed by FeaturePolicyParser which returns an
+ * array of Feature objects. Each Feature object has a feature name and one of
+ * these policies:
+ * - eNone - the feature is fully disabled.
+ * - eAll - the feature is allowed.
+ * - eAllowList - the feature is allowed for a list of origins.
+ *
+ * An interesting element of FeaturePolicy is the inheritance: each context
+ * inherits the feature-policy directives from the parent context, if it exists.
+ * When a context inherits a policy for feature X, it only knows if that feature
+ * is allowed or denied (it ignores the list of allowed origins for instance).
+ * This information is stored in an array of inherited feature strings because
+ * we care only to know when they are denied.
+ *
+ * FeaturePolicy can be reset if the 'allow' or 'src' attributes change in
+ * HTMLIFrameElements. 'src' attribute is important to compute correcly
+ * the features via FeaturePolicy 'src' keyword.
+ *
+ * When FeaturePolicy must decide if feature X is allowed or denied for the
+ * current origin, it checks if the parent context denied that feature.
+ * If not, it checks if there is a Feature object for that
+ * feature named X and if the origin is allowed or not.
+ *
+ * From a C++ point of view, use FeaturePolicyUtils to obtain the list of
+ * features and to check if they are allowed in the current context.
+ *
+ * dom.security.featurePolicy.header.enabled pref can be used to disable the
+ * HTTP header support.
