Update to working draft

Gregg pointed out this seems to have become a little mangled:

"Other supported systems include GPII, ISO, Cload4All and possibly Fluid."‏

ISO is a standards org - not a system and Cloud4all is a subset of GPII‏

so perhaps

"Other supported standards and systems of interest include ISO,
Cloud4All/Prosperity4All/GPII and possibly Fluid."‏
