Has anybody actually asked Ray to get such a permanent part of IETF's own web space allocated and setup? Would entries on the web site require IANA assignment, e.g. as a registry? I'm asking because I am new to the discussion, and simply don't know the answer. dbh > -----Original Message----- > From: Scott Hollenbeck [mailto:sah-ietf@tengwar.com] > Sent: Friday, January 04, 2008 11:04 AM > To: 'Julian Reschke' > Cc: 'Apps Discuss' > Subject: RE: URI for XML schema and namespace > > > -----Original Message----- > > From: Julian Reschke [mailto:julian.reschke@gmx.de] > > Sent: Friday, January 04, 2008 10:54 AM > > To: Scott Hollenbeck > > Cc: 'tom.petch'; 'Apps Discuss' > > Subject: Re: URI for XML schema and namespace > > > > Scott Hollenbeck wrote: > > >> -----Original Message----- > > >> From: tom.petch [mailto:cfinss@dial.pipex.com] > > >> Sent: Friday, January 04, 2008 8:19 AM > > >> To: Apps Discuss > > >> Subject: URI for XML schema and namespace > > >> > > >> What is the currently recommended form for a URI for an > XML schema > > >> and an XML namespace? > > >> > > >> The question has come up on ForCES where I, citing > RFC3688 say it > > >> should be urn: > > >> whereas the others cite RFC3470 to say that http: is recommended. > > >> > > >> Other opinions welcome. > > > > > > Those folks looking at 3470 might have missed the third > > paragraph in > > > section > > > 4.9: > > > > > > "In the case of namespaces in IETF standards-track > > documents, it would > > > be useful if there were some permanent part of the IETF's own web > > > space that could be used for this purpose.
