It's just badly phrased. Here's improved wording:
The "version" reports the version of the database schema. Because
this is a recent addition to the schema format, OVSDB permits it
to be omitted, but future versions of OVSDB will require it to be
present. Open vSwitch semantics for "version" are described in
ovs-vswitchd.conf.db(5).
