	// generated by that operation will have ClientRequestToken set as token1.

	// In the console, stack operations display the client request token on the
	// Events tab. Stack operations that are initiated from the console use the
	// token format Console-StackOperation-ID, which helps you easily identify the
	// stack operation . For example, if you create a stack using the console, each
	// stack event would be assigned the same token in the following format: Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002.
