I wrote that draft kind of quickly in order to get it under the deadline and start this discussion. Correct me if I'm wrong here: so it is always the case that, in order to parse some XML according to a DTD and the SYSTEM literal is a URI, then I must have connectivity in order to download the DTD? In that case, how are names for DTD standardized? I rarely see anyone related to XML using a PUBLIC identifier. They all tend to use the SYSTEM id as some sort of name instead. I can easily deprecate assigning a URN to a DTD in this spec. But it does raise the issue of what the suggested practice from the W3C is. > | I'm not sure where this leaves us - in the land of rarely-deployed > | architecture, I suspect. > > I suppose.

Whether you give up or not, people will start using addresses as names whether its possible to do so or not. -MM -- -------------------------------------------------------------------------------- Michael Mealling | Vote Libertarian! | www.rwhois.net/michael Sr. Research Engineer | www.ga.lp.org/gwinnett | ICQ#: 14198821 Network Solutions | www.lp.org | michaelm@n... ----- End forwarded message ----- -- -------------------------------------------------------------------------------- Michael Mealling | Vote Libertarian! | www.rwhois.net/michael Sr. Research Engineer | www.ga.lp.org/gwinnett | ICQ#: 14198821 Network Solutions | www.lp.org | michaelm@n...
