@@ -55,12 +55,13 @@ The ``[version]`` argument requests a version with which the package found
 should be compatible. There are two possible forms in which it may be
 specified:
 
-  * A single version with the format ``major[.minor[.patch[.tweak]]]``.
+  * A single version with the format ``major[.minor[.patch[.tweak]]]``, where
+    each component is a numeric value.
   * A version range with the format ``versionMin...[<]versionMax`` where
-    ``versionMin`` and ``versionMax`` have the same format as the single
-    version.  By default, both end points are included.  By specifying ``<``,
-    the upper end point will be excluded.  Version ranges are only supported
-    with CMake 3.19 or later.
+    ``versionMin`` and ``versionMax`` have the same format and constraints
+    on components being integers as the single version.  By default, both end
+    points are included.  By specifying ``<``, the upper end point will be
+    excluded. Version ranges are only supported with CMake 3.19 or later.
 
 The ``EXACT`` option requests that the version be matched exactly. This option
 is incompatible with the specification of a version range.
