The easiest way I've found to identify things is to just perform an AppiumDriver.getPageSource() in your test code for the pages you want to inspect and have it copied to the clipboard, and then paste it into your favorite XML viewer.
I've ended up doing this even on Appium 1.5.3, as I've found the locator to be inaccurate much of the time for the app I'm testing on iOS and Android.
