Isn't this also the mode of WinHelp?  WinHelp uses a restricted target 
set (footnotes in page delimited chunks), but the rest of the
is topical based on the project file (defines the objects whose topics 
are targets) and the #define files (string and paired ID) for the 
software to use for contextual help, and the compiled files.

How does Panorama store linking information?

Well, not just when, but how is it packed if it is in separate files for 
different processors?  Consider the winHelp model.  I ask because my 
guess is a very high percentage of the legacy hypertext in the world 
right now in need of conversion is WinHelp.  That means taking the 
separate pieces and mapping them to the XML-n models.
