+	<longdescription>
+	Cached descriptors cache their output. They take into account instance attributes that they depend on, so when the instance attributes change, the descriptors will change the values they return.
+
+	Cached descriptors cache their data in _v_ attributes, so they are also useful for managing the computation of volatile attributes for persistent objects.
+
+	Persistent descriptors:
+
+	property
+
+	A simple computed property.
+
+	See src/zope/cachedescriptors/property.rst.
+
+	method
+
+	Idempotent method. The return values are cached based on method arguments and on any instance attributes that the methods are defined to depend on.
+
+	Note
+
+	Only a cache based on arguments has been implemented so far.
+
+	See src/zope/cachedescriptors/method.rst.
