I have not just hinted at it, I advocate it as a way to allow proper processing of links by browsing applications, which are our prototypical example of an application that does not need a DTD. And of course, with a different notion of stylesheet, other forms of application processing than browsing might also be accomodated without a DTD. If you want to _analyse_ link relationships, then I think a requirement to fetch the DTD is reasonable. What I really want is to use architectural forms and default attribute values, but not require authors to put defaultable attribute values in their instances for the benefit of DTD-challenged applications. XML browsers will almost certainly require stylesheets anyway, so that adding linking to the stylesheet allows link behavior to be preserved, in just the case where _all_ you really care about is behavior. No application should have to analyze a turing-complete script to determine if it invokes link behavior or not. There must always be some _declarative_ way to determine if a random piece of markup is a link. -- David I am not a number.
