The ifeval directives used in the upstream docs to distinguish upstream content vs. downstream content do not render downstream. Example:

ifeval::["\{build}" == "upstream"]

OVSDB_IMAGE=quay.io/podified-antelope-centos9/openstack-ovn-base:current-podified

endif::[]

ifeval::["\{build}" == "downstream"]

OVSDB_IMAGE=registry.redhat.io/rhosp-dev-preview/openstack-ovn-base-rhel9:18.0

endif::[]

I determined that this can be fixed as a stop-gap downstream by using "ifdef" and "ifndef" directives instead. E.g.,

ifdef::upstream[]

ifndef::downstream[]

However, this solution cannot be used upstream. We need a solution that works when copying files from upstream to downstream and vice versa.
