Which implies that references would be through links rather than entity
references and that the focus is not the document, but the element,
element-range, or whatever link semantic the OS implements. If the "standard"
link is to the root element, then it would have the same effect as the file
systems which have distinguish resource from data forks or support file
headers, but provide the "data" as the standard file content. It would be XML,
just not literal XML.
