+ * @ngdoc service
+ * @name $sanitize
+ * @kind function
+ *
+ * @description
+ *   Sanitizes an html string by stripping all potentially dangerous tokens.
+ *
+ *   The input is sanitized by parsing the HTML into tokens. All safe tokens (from a whitelist) are
+ *   then serialized back to properly escaped html string. This means that no unsafe input can make
+ *   it into the returned string.
+ *
+ *   The whitelist for URL sanitization of attribute values is configured using the functions
+ *   `aHrefSanitizationWhitelist` and `imgSrcSanitizationWhitelist` of {@link ng.$compileProvider
+ *   `$compileProvider`}.
+ *
+ *   The input may also contain SVG markup if this is enabled via {@link $sanitizeProvider}.
+ *
+ * @param {string} html HTML input.
+ * @returns {string} Sanitized HTML.

+ * @ngdoc filter
+ * @name linky
+ * @kind function
+ *
+ * @description
+ * Finds links in text input and turns them into html links. Supports `http/https/ftp/mailto` and
+ * plain email address links.
+ *
+ * Requires the {@link ngSanitize `ngSanitize`} module to be installed.
+ *
+ * @param {string} text Input text.
+ * @param {string} target Window (`_blank|_self|_parent|_top`) or named frame to open links in.
+ * @param {object|function(url)} [attributes] Add custom attributes to the link element.
+ *
+ *    Can be one of:
+ *
+ *    - `object`: A map of attributes
+ *    - `function`: Takes the url as a parameter and returns a map of attributes
+ *
+ *    If the map of attributes contains a value for `target`, it overrides the value of
+ *    the target parameter.
+ *
+ *
+ * @returns {string} Html-linkified and {@link $sanitize sanitized} text.
