The current behavior works fine, my question was whether relative paths 
outside the install prefix (i.e. paths starting with one or more "..") 
were officially sanctioned / officially discouraged.  This comes-up 
occasionally with the bundle generator, anytime someone wants to write a 
file outside the Resources directory (which is where the bundle 
generator maps the install prefix).

Cheers,
Tim
