There isn't a standard way so this was the compromise. I could join the UEFI forum IRC and inquire about it but I wouldn't be surprised if it's a "there is no standard" solution. My thinking was this would at least be an easily recognizable way programs could access the UEFI stuff if they need it for things like graphics or networking.
