Creates an OWASP policy with no rules. Rules can be added like so: def allowAttributesOnElems(attrs: List[String], elems: List[String]): OWaspPolicy def allowAttributesGlobally(attrs: List[String]): OWaspPolicy def disallowAttributesOnElems(attrs: List[String], elems: List[String]): OWaspPolicy def disallowAttributesGlobally(attrs: List[String]): OWaspPolicy def allowElements(elems: List[String]): OWaspPolicy def allowTextIn(elems: List[String]): OWaspPolicy def disallowTextIn(elems: List[String]): OWaspPolicy def requireReslOnLinks(links: List[String]): OWaspPolicy def skipRelsOnLinks(links: List[String]): OWaspPolicy def allowUrlProtocols(protocols: List[String]): OWaspPolicy def disallowUrlProtocols(protocols: List[String]): OWaspPolicy def allowWithoutAttributes(elems: List[String]): OWaspPolicy def disallowWithoutAttributes(elems: List[String]): OWaspPolicy def disallowElements(elems: List[String]): OWaspPolicy def allowStandardUrlProtocols: OWaspPolicy def allowCommonInlineFormattingElements: OWaspPolicy def allowCommonBlockElements: OWaspPolicy def requireRelNofollowOnLinks: OWaspPolicy def allowStyling: OWaspPolicy def allowStyling(properties: List[String]): OWaspPolicy def allowStylingWithDefault(properties: List[String]): OWaspPolicy def allowUrlsInStyles(elemAttrValueFunc: Tuple3[String, String, String] => String): OWaspPolicy def withPreProcessor( onOpenDocument: () => Unit = () => {}, onCloseDocument: () => Unit = () => {}, onOpenElement: Tuple2[String, List[String]] => Unit = (t: Tuple2[String, List[String]]) => Unit, onCloseElement: String => Unit = (s: String) => Unit, onText: String => Unit = (s: String) => Unit ): OWaspPolicy def withPostProcessor( onOpenDocument: () => Unit = () => {}, onCloseDocument: () => Unit = () => {}, onOpenElement: Tuple2[String, List[String]] => Unit = (t: Tuple2[String, List[String]]) => Unit, onCloseElement: String => Unit = (s: String) => Unit, onText: String => Unit = (s: String) => Unit ): OWaspPolicy
