Nice. But I don't think that it does the same thing: my proposal provides an alternate syntax for internal entities which also allows bundled other documents. (Thinking about it more, it suggests that it might fill some nice needs if the entity mechanism was rejigged to allow appendable entities rather than having them in a prolog.) I think you would need to have some top-level attribute available to say "this branch does not form part of the infoset" so that it can be referenced from an XInclude without appearing in the document twice (assuming we will perform some kind of XInclude linking early).
