+      For each built-in datatype in this schema (both primitive and
+      derived) can be uniquely addressed via a URI constructed
+      as follows:
+        1) the base URI is the URI of the XML Schema namespace
+        2) the fragment identifier is the name of the datatype
+
+      For example, to address the int datatype, the URI is:
+
+        http://www.w3.org/2001/XMLSchema#int
+
+      Additionally, each facet definition element can be uniquely
+      addressed via a URI constructed as follows:
+        1) the base URI is the URI of the XML Schema namespace
+        2) the fragment identifier is the name of the facet
+
+      For example, to address the maxInclusive facet, the URI is:
+
+        http://www.w3.org/2001/XMLSchema#maxInclusive
+
+      Additionally, each facet usage in a built-in datatype definition
+      can be uniquely addressed via a URI constructed as follows:
+        1) the base URI is the URI of the XML Schema namespace
+        2) the fragment identifier is the name of the datatype, followed
+           by a period (".") followed by the name of the facet
+
+      For example, to address the usage of the maxInclusive facet in
+      the definition of int, the URI is:
+
+        http://www.w3.org/2001/XMLSchema#int.maxInclusive
