-        This is a constant value and MUST be ``1``, when using the
-        schema described here. Future iterations of this schema MUST
-        update this value.
+        This is a string following the format ``<MAJOR>.<MINOR>``, where
+        ``<MAJOR>`` and ``<MINOR>`` are unpaded numbers and represent
+        the **major** and **minor** components of the version. Versions
+        may be arithmetic compared by intrepreting the version string as
+        a decimal number.
+
+        For this specification version, this value is constant and MUST
+        be ``1.0``.
+
+        Future versions of this schema MUST use a higher version number.
+        Future versions of this schema MUST NOT use the same **major**
+        version component as other schema version unless its
+        specification is deemed backwards-compatible with them — it
+        can't change, or extend, any parts of the current specification
+        in such a way as the semantics of the interpreted data differ,
+        or that data valid under the new specification is invalid under
+        the older specification, with the exception of additional
+        properties (errors caused by ``additionalProperties``).
