True enough.... though I think this boils down to an issue of packaging and specification. The "standalone" hack in XML is, in some ways, a step in the right direction, in that it tells the system that we need a bit more than just this instance.
A good packaging mechanism (meaning more than just the physical packaging) such as XAR+ would allow the person producing the document to put all the needed bits and pieces together.
I'm trying to remember when people started assuming that a naked instance was in and of itself useful.... when the XML activity was kicked off, the charter explicitly included bits that would make XML actually useful as a generic markup language (stylesheets and linking in particular). Somewhere along the line, we lost focus of the need for things to *process* XML as part of the application.
