Referring to the reference data for Ad Position (Section 6.4) and No-Bid Reason
(Section 6.6), each has a value 0 that means “unknown”. However, a broad
concept throughout OpenRTB attributes, other than block or white lists, is that
an omitted optional attribute means “unknown”. For this reason, other
attributes do not have an explicit value to mean “unknown”. For
consistency, these should be removed as well.
The 0 = unknown value existed in the OpenRTB Mobile specification for No-Bid
reason, but since an exchange would likely also interpret an undefined value as
“unknown”, this should not cause a backward compatibility issue.
