  - `formspec_ast.safe_parse(string_or_tree)`: Similar to `formspec_ast.parse`,
     however will delete any elements that may crash the client (or any I
     haven't added to the whitelist).
+ - `formspec_ast.formspec_escape(text)`: The same as `minetest.formspec_escape`,
+    should only be used when formspec_ast is being embedded outside of Minetest.
