  Re: Progress so far, and a new header
 
(...) Ahh, good idea. The URLs for the articles are less stable than the Xref lines are. For example, when the new web-interface/hierarchy is moved into place, shortly after that will come a remapping of all the article URLs (but the old ones will (...) (25 years ago, 7-May-99, to lugnet.faq)
 
  Re: Progress so far, and a new header
 
(...) I was afraid of that. :-, (...) I'm prone to just go with the simpler form, copying the X-Ref header, for several reasons: a) I don't have to enter the Web interface and search for messages to find the URL, b) The URL can be automagically (...) (25 years ago, 7-May-99, to lugnet.faq)

(...) It's a semantic difference. - 'References' refers to other articles (ancestors). - 'Xref' is self-referential and refers both to itself and to any other copies of the same article if it has been crossposted. So copying the 'Xref' header (and (...) (25 years ago, 13-May-99, to lugnet.faq)
