I am not sure what you mean - the es53.js in combination with the rewriter simulates ES5-strict mode including the addition functions that come with ES5 like Object.create and Object.defineProperty on ES3 browsers. We do not have a pure js solution that targets ES3 browsers. For browsers that do support ES5, SES is a pure javascript implementation. We're in the process of pulling in SES to the caja trunk http://codereview.appspot.com/4249052.
