-		//
-		//		If you want the browser location string to change, define "changeUrl" on the object. If the
-		//		value of "changeUrl" is true, then a unique number will be appended to the URL as a fragment
-		//		identifier (http://some.domain.com/path#uniquenumber). If it is any other value that does
-		//		not evaluate to false, that value will be used as the fragment identifier. For example,

-		//	BROWSER NOTES:
-		//  Safari 1.2: 
-		//	back button "works" fine, however it's not possible to actually
-		//	DETECT that you've moved backwards by inspecting window.location.
-		//	Unless there is some other means of locating.
-		//	FIXME: perhaps we can poll on history.length?
-		//	Safari 2.0.3+ (and probably 1.3.2+):
-		//	works fine, except when changeUrl is used. When changeUrl is used,
-		//	Safari jumps all the way back to whatever page was shown before
-		//	the page that uses dojo.undo.browser support.
-		//	IE 5.5 SP2:
-		//	back button behavior is macro. It does not move back to the
-		//	previous hash value, but to the last full page load. This suggests
-		//	that the iframe is the correct way to capture the back button in
-		//	these cases.
-		//	Don't test this page using local disk for MSIE. MSIE will not create 
-		//	a history list for iframe_history.html if served from a file: URL. 
-		//	The XML served back from the XHR tests will also not be properly 
-		//	created if served from local disk. Serve the test pages from a web 
-		//	server to test in that browser.
-		//	IE 6.0:
-		//	same behavior as IE 5.5 SP2
-		//	Firefox 1.0+:
-		//	the back button will return us to the previous hash on the same
-		//	page, thereby not requiring an iframe hack, although we do then
-		//	need to run a timer to detect inter-page movement.
