Multiple partitions on the same drive is just multiplying the chances of problems and if the drive goes you are two sytems down, not one.
Solutions for accessing Appleworks .cwk files in El Capitan:
You insist upon making a recommendation that is neither supported by user experience and is contrary to the opinions of various "experts" who, like you, reside here on the Apple Support Communities. While the bulk of the evidence is against your position, you insist on clouding the issue with all sorts of ancillary arguments.
The fact of the matter is that, other than you, there is no groundswell of opinion on the Apple Support Communities that partitioning the internal drive of a Mac will lead to its ultimate failure. I have given you various cites to other known "experts" here on the Apple Support Communities (which, according to your profile, you joined on July 6, 2008) that comfortably advise others to either partition their internal hard drives, or optionally, use an external hard drive. You have chosen to ignore these well known members of these Communities.
Your advice is also that a bootable external drive is always valuable to have in case of internal hard drive failure, and most everyone would agree that is good backup strategy for any Mac user, irrespective of whether they partition their internal hard drive or not.
I am sure you are the "expert" of all things Pages.
In certain circumstances, Pages, will provide a solution for Mac users who need to access their Appleworks files once they have upgraded to El Capitan. However there are two additional available "solutions" for people who need to access their Appleworks files in El Capitan:
1) In those situations, where the user upgraded to El Capitan from a Mac that can boot Snow Leopard, either create a new partition or use an external drive and install Snow Leopard there and use the "dual-boot" method to access Appleworks in Snow Leopard as needed; and
2) To the extent that the user cannot run Snow Leopard on his Mac or needs access to Appleworks concurrently with running El Capitan, install Snow Leopard Server into a virtualization program, such as Parallels and run Appleworks concurrently in El Capitan:

Anything else just clouds the issue for the end users to choose which is the best solution for their needs.
