For example, consider an empty document in which you create some objects. Then you select all of them and press 'delete'. This effectively brings the document into the original clean state, but the undo history is non-empty. That's why you are asked for confirmation when you want to exit, although there is nothing to save. I was wondering if there is a way to detect such situations, for example by using MD5 hashes as suggested by Thomas Worthington.
Well, that is possible - we even have an RFE for that I think - but it would be a very superficial nicety, costing a lot more trouble in implementing than it would bring benefits. Besides it would be fundamentally unreliable, because there are many aspects of XML that can be changed without actually changing the document, such as the order of attributes.
