 Ranges of numbers are specified using a combination of the
-``minimum``, ``maximum``, ``exclusiveMinimum`` and
-``exclusiveMaximum`` keywords.
+``minimum`` and ``maximum`` keywords (or ``exclusiveMinimum`` and
+``exclusiveMaximum`` for expressing exclusive range).
 
-- ``minimum`` specifies a minimum numeric value.
+- ``minimum`` specifies an inclusive lower limit for a numeric instance,
+  i.e., :math:`x \ge\mathrm{min}`.
+
+- ``exclusiveMinimum`` specifies an exclusive lower limit for a numeric instance,
+  i.e., :math:`x > \mathrm{min}`.  
 
-- ``exclusiveMinimum`` is a boolean.  When ``true``, it indicates that
-  the range excludes the minimum value, i.e., :math:`x >
-  \mathrm{min}`.  When ``false`` (or not included), it indicates that
-  the range includes the minimum value, i.e., :math:`x \ge
-  \mathrm{min}`.
-
-- ``maximum`` specifies a maximum numeric value.
-
-- ``exclusiveMaximum`` is a boolean.  When ``true``, it indicates that
-  the range excludes the maximum value, i.e., :math:`x <
-  \mathrm{max}`.  When ``false`` (or not included), it indicates that
-  the range includes the maximum value, i.e., :math:`x \le
-  \mathrm{max}`.
