IndexedDB API Doc Correction

Hello,

I have a quick document correction for:  http://www.w3.org/TR/IndexedDB/

As far as I can tell, there is no "openIndex" method as shown in the "var
index" example below.  I think it should be objectStore.index() ?  Also, I
am assuming that the var vtx is a versionchange transaction object, but vtx
is not defined anywhere else in the documentation.  Just figured I would
pass these along :)

3.3.4 Index

var db = indexedDBSync.open('AddressBook', 2, function(trans, oldVersion) {
  if (oldVersion === 1) {
    trans.db.createObjectStore('Contact', {keyPath:'id', autoIncrement:true});
  }
  var store = vtx.objectStore('Contact');
  store.createIndex('ContactName', {unique:false, multiEntry:false});
});

var index = store.openIndex('ContactName');
var id = index.get('Lincoln');
// id === 1
