You would find that CMS enforces the restriction of 0-6. The phrase "reserved" means "don't even *think* about it". There is no hint of what our ancestors might have had in mind for 7, 8, and 9. I'm guessing number 9 was for files backed by a quantum singularity server, allowing them to be shared among multiple universes (up to 8) and their updates seen instantly. -- Chuckie
