I was trying to think whether we need a conformance statement
stating so. I guess this is up to the device?
Then let's make it clear. Something like:
	For the SR-IOV group type,
	the owner device supporting legacy configuration access commands
	[assuming this is the term - do we define it somewhere? or just
	list the commands]
	MAY follow the rules for the PCI Device ID, Revision ID
	and Subsystem Device ID for the non-transitional devices
	documented in
	{Virtio Transport Options / Virtio Over PCI Bus / PCI Device Discovery}

or do you want to make it a SHOULD?
