trustedTypes

["Kevin Carhart" <kevin_carhart@fastmail.fm>]

This is what I have so far for the trustedTypes API.  There may be issues but here's what I came up with.

trustedTypes = function(){};
trustedTypes.createPolicy = function(pn,po){
var x = new Object;
x.policyName = pn;
if (po['createHTML'])
x.createHTML = po['createHTML'];
if (po['createScript'])
x.createScript = po['createScript'];
if (po['createScriptURL'])
x.createScriptURL = po['createScriptURL'];
return x;
}

This is the code that uses it in the recaptcha library.  Later code will expect to be able to get those callback names and run them.

                if (B = O, (u = G.trustedTypes) && u.createPolicy) {
                    try {
                        B = u.createPolicy('goog#html', {
                            createHTML: a[W].bind(v[0], A),
                            createScript: a[W].bind(v[0], v[2]),
                            createScriptURL: a[W].bind(v[0], v[1])
                        });
