Drat. I probably misunderstood. Thought a silver bullet might have been
sitting around somewhere.

The XLL specs (XLink/XPointer) do look good. (more below),

Another tutorial that is geared towards Java programmers, but which also
has an XML-only thread, is available at
http://java.sun.com/xml/tutorial_intro.html
Here's the section on XLink from that page:
--- The XLink protocol is a proposed specification to handle links between XML documents. This specification allows for some pretty sophisticated linking, including two-way links, links to multiple documents, "expanding" links that insert the linked information into your document rather than replacing your document with a new page, links between two documents that are created in a third, independent document, and indirect links (so you can point to an "address book" rather than directly to the target document -- updating the address book then automatically changes any links that use it). ---The indirect links look particularly useful, as do the multiple-document links and expanding links.
One question, though: How do you establish link "types" in XML? For example: How do you mark a link to suggest that it should be traversed in a separate window, rather than in the same window?
