I was looking at the way that the CoreMessaging uses Javascript and there are a couple of things I've run into that I"m trying to understand.

1) I see that the javascript often references an object called "ko" but I don't see where this gets created.   What is "ko" and is there any documentation on it?

 2) Is there any documentation for the "ServicesFramework" object?

 3) The coremessaging script references the Service framework with "$.ServicesFramework(416)"   What is the significance of the 416

 Thanks
