     Golden Orchard has one ProDOS volume (which can be booted) and six 
HFS volumes. (HFS file names can be long and may include 
non-letter/number characters.)

     According to the GS/OS Reference, the High Sierra Group and ISO 9660 
formats are nearly identical. It does not mention ISO 9660 version.

     The High Sierra File System Translator supports long file names 
which can contain upper-case letters, digits 0-9, and the underscore 
character. Non-directory file identifiers can have three parts: file 
name, name extension, version number. The file name, a period, and the 
name extension can sum to 31 characters. HS.FST allows a non-directory 
file identifier to consist of just the file name or just the name 
extension. 

     Subdirectories and associate files (e.g. resources) are supported. 
Multiple volumes and multi-session are not supported. HS.FST supports 
reads but not writes.
