+ * @kind function
+ *
+ * @description
+ * The input is sanitized by parsing the html into tokens. All safe tokens (from a whitelist) are
+ * then serialized back to properly escaped html string. This means that no unsafe input can make
+ * it into the returned string, however, since our parser is more strict than a typical browser
+ * parser, it's possible that some obscure input, which would be recognized as valid HTML by a
+ * browser, won't make it through the sanitizer.
+ * The whitelist is configured using the functions `aHrefSanitizationWhitelist` and
+ * `imgSrcSanitizationWhitelist` of {@link ng.$compileProvider `$compileProvider`}.
+ *
+ * @param {string} html Html input.
+ * @returns {string} Sanitized html.
