The current version of the URN draft suggests that the ISBN numbers
(and other previously assigned, widely recognized naming conventions) can
be grandfathered into the URN scheme by assigning a naming authority scheme
which reflects that naming scheme. Something like

(Using the old clunky syntax)

URN:ISBN:[ISBN_Publisher_ID]::[Rest of ISBN number]:::

Does this allay your concerns about having one style of URN, or does this need to be different?
