https://datatracker.ietf.org/doc/html/draft-krishnaswamy-dnsop-dnssec-split-view
uses it two or three times.
I used that term because it was part of the draft.
It wasn't a term I knew before.
It doesn't explain the term (that I saw), so I figured it was simply unknown
to me.

I have chosen to think that it's a situation where there is an NS record
for a subdomain which does not answer queries from the world.  That could be
a matter of policy (ACLs), or because the query point is not globally
routable (RFC1918, ULAs, ...)
