This illustrates that the semantics of an XML instance may be substantially different for different users, and that those semantic differences are elaborated by the local processing applied for their own different purposes by those users. In performing that processing, users have clues outside of the canonical infoset of XML--in this case document order (and document order of the DTD, if applicable). The needs of each user are as they are and, given necessity, the user must find a means of local processing which meets those needs while working with an XML instance as received. I believe that this demonstrates how the creator or transmitter of an XML instance should not presume what the semantic outcome of that instance will be in the hands of a user and, more particularly, never expect that an XML instance--whatever standards it might be created to--conveys specific semantics. It is in the nature of XML that it will be processed anew by each recipient. Given that the outcome of that processing must met the local needs of each user, we must expect that processing to be locally idiosyncratic.
