Perhaps I am still missing something in my understanding about transclusion. I believe in these Principles: (1) Any author should be allowed to withdraw or edit any part of his text at any time. (2) No author should be able to alter another's original text, but should be allowed to excerpt, quote and highlight passages. Given these two principles, what if Author A modifies his text after Author B writes a criticism of it in which he transcludes part of the original text? What if Author A's modification deletes or modifies the portion of the text which Author B's document criticizes? This renders the review obsolete (and perhaps moot). With Transclusion, presumably Author B would be informed of Author A's modifications, and have the option of revising his review. If the changes by Author A substantially alter the content of the document (e.g. deleting a paragraph which Author B found offensive) then the updates to Author B's document cannot be done automatically, because they necessitate Author B's human consideration of the changed meaning. What happens if Author B is on vacation? [Jay Osako] My understanding is that document b still points to document a, which (under Xanadu) is still available. if author B wants to comment on the modified document a', then he'd write the new commentary c (possibly linking it to b to make b') and link it to a'. It is possible, however, to link to a second link instead of a document directly however. If the 'handle' (I thnk there is a special term for this, but I can't recall it) points to the link 'section a@ of current version of a', then the newest version is included instead of the one current when it was made. On the user's end, they'd select something like 'hot link' or 'update automatically' when making the link, and that would be it. Is this more or less correct by the current desing, or am I wrong? Jay
