Sorry, I confused some terminology: what are called the Node structures
are implemented as "subtables" in the ACPI reference implementation
(ACPICA). But yes, I've proposed the v8 version.

Merci, Jean-Philippe :). I'll point the individual at you and the
iommu mailing list, and the CCs. Sadly, I did not write down the
full question, nor the person's name (from Microsoft, possibly?)
and now seem to have completely forgotten both (it's been a long
few months...). If I can find something in the meeting minutes,
I'll pass that on.
Thanks again for everyone's patience.
