+Transitional Driver Conformance} +A conformant implementation MUST be either transitional or +non-transitional, see \ref{sec:Basic Facilities of a Virtio +Device / Feature Bits / Legacy Interface: A Note on transitions +from earlier drafts}. + +A non-transitional implementation conforms to this specification +if it satisfies all of the MUST or REQUIRED level requirements +defined above. + +An implementation MAY choose to implement OPTIONAL support for the +legacy interface, including support for legacy drivers +or devices, by additionally conforming to all of the MUST or +REQUIRED level requirements for the legacy interface +for the transitional devices and drivers. + +The requirements for the legacy interface for transitional implementations +are located in sections named "Legacy
