+
+            Note that local names in this namespace are intended to be defined
+            only by the World Wide Web Consortium or its subgroups.  The
+            following names are currently defined in this namespace and should
+            not be used with conflicting semantics by any Working Group,
+            specification, or document instance:
+
+            base (as an attribute name): denotes an attribute whose value
+            provides a URI to be used as the base for interpreting any
+            relative URIs in the scope of the element on which it
+            appears; its value is inherited.  This name is reserved
+            by virtue of its definition in the XML Base specification.
+
+            id   (as an attribute name): denotes an attribute whose value
+            should be interpreted as if declared to be of type ID.
+            The xml:id specification is not yet a W3C Recommendation,
+            but this attribute is included here to facilitate experimentation
+            with the mechanisms it proposes.  Note that it is _not_ included
+            in the specialAttrs attribute group.
+
+            lang (as an attribute name): denotes an attribute whose value
+            is a language code for the natural language of the content of
+            any element; its value is inherited.  This name is reserved
+            by virtue of its definition in the XML specification.
+
+            space (as an attribute name): denotes an attribute whose
+            value is a keyword indicating what whitespace processing
+            discipline is intended for the content of the element; its
+            value is inherited.  This name is reserved by virtue of its
+            definition in the XML specification.
+
+            Father (in any context at all): denotes Jon Bosak, the chair of
+            the original XML Working Group.  This name is reserved by
+            the following decision of the W3C XML Plenary and

+            attributes on elements they define.
+
+            To enable this, such a schema must import this schema

+
+            Subsequently, qualified reference to any of the attributes
+            or the group defined below will have the desired effect, e.g.
+
+            &lt;type . . .>
+            . . .
+            &lt;attributeGroup ref="xml:specialAttrs"/>
