Is the issue in relaying a header 'as is,' i.e., when a header is processed by an intermediary then forwarded without modification. However, if a header were processed, then modified and forwarded, it would seem intuitive (to me) that preservation of the prefixes would not apply. Is that a fair assessment? -Matt Long > -----Original Message----- > From: xml-dist-app-request@w3.org [mailto:xml-dist-app-request@w3.org] On > Behalf Of Noah Mendelsohn/Cambridge/IBM > Sent: Tuesday, February 11, 2003 6:55 PM > To: mlong@phalanxsys.com > Cc: 'David Fallside'; 'Martin Gudgin'; 'Sanjiva Weerawarana'; xml-dist- > app@w3.org > Subject: RE: treatment of ns prefixes by intermediaries > > > > I assume that 'preserve' and 'reuse' are distinct, > > i.e., that an intermediary is not required to 'reuse' > > prefixes for inserted headers. > > I think Matt raises an interesting question.
