- * @fileoverview Type-safe wrappers for unsafe DOM APIs.
- *
- * This file provides type-safe wrappers for DOM APIs that can result in
- * cross-site scripting (XSS) vulnerabilities, if the API is supplied with
- * untrusted (attacker-controlled) input. Instead of plain strings, the type
- * safe wrappers consume values of types from the goog.html package whose
- * contract promises that values are safe to use in the corresponding context.
- *
- * Hence, a program that exclusively uses the wrappers in this file (i.e., whose
- * only reference to security-sensitive raw DOM APIs are in this file) is
- * guaranteed to be free of XSS due to incorrect use of such DOM APIs (modulo
- * correctness of code that produces values of the respective goog.html types,
- * and absent code that violates type safety).
- *
- * For example, assigning to an element's .innerHTML property a string that is
- * derived (even partially) from untrusted input typically results in an XSS
- * vulnerability. The type-safe wrapper goog.html.setInnerHtml consumes a value
- * of type goog.html.SafeHtml, whose contract states that using its values in a
- * HTML context will not result in XSS. Hence a program that is free of direct
- * assignments to any element's innerHTML property (with the exception of the
- * assignment to .innerHTML in this file) is guaranteed to be free of XSS due to
- * assignment of untrusted strings to the innerHTML property.
