I would say that /domain/os/bios/pm isn't the correct place because /domain/os relates only to OS booting while Power Management is outside of the scope of booting. In fact /domain/os/bios simply controls whether the BIOS output will be over VGA or over serial. Features specific to the system are typically kept as top level items, which matches /domain/pm. I would however say that using the terms ACPI, s3 and s4 isn't good design for the XML. You can leave that to documentation but /domain/pm/suspend-to-mem and /domain/pm/suspend-to-disk are better so that the same XML structure can be used for PPC. They have concepts similar to s3 and s4 (I only briefly Googled this) but they're named completely differently. The only under place I could see this would be /domain/features/acpi. If its there then s3 and s4 potentially make sense, but then we're left without a place for PPC to tie in.
