I skim-searched a dodgy source known to contain weird
and wonderful
 standards
 documents and other tech references that are still under copyright so
 tend not
 to be on the surface web. Sadly, the title you want didn't turn up, but
 "Eisa
 System Architecture" (020140995X) did. It's not a standards document,
 but the
 second half of chapter 9 discusses CFG files and gives an example
 including a
 breakdown of what the fields mean, which might be enough to get you
 going. 
Peter,
Thanks for checking. I was able to borrow a copy of the book from the
Internet Archive and looked through the pertinent chapter. While it does do
a nice illustration of a CFG file it does not address any questions on
specifics. I may still pick up the book to have as a reference although it
seems aimed mostly at the HW guys. Thanks for the pointer!
