-   See http://www.w3.org/XML/1998/namespace.html and
-   http://www.w3.org/TR/REC-xml for information about this namespace.
-
-    This schema document describes the XML namespace, in a form
-    suitable for import by other schema documents.  
-
-    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.
-         This name is reserved by virtue of its definition in the
-         xml:id specification.
-
-    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 
-         XML Coordination groups:
-
-             In appreciation for his vision, leadership and dedication
-             the W3C XML Plenary on this 10th day of February, 2000
-             reserves for Jon Bosak in perpetuity the XML name
-             xml:Father

-
- <xs:annotation>
-  <xs:documentation>This schema defines attributes and an attribute group
-        suitable for use by
-        schemas wishing to allow xml:base, xml:lang, xml:space or xml:id
-        attributes on elements they define.
-
-        To enable this, such a schema must import this schema
-        for the XML namespace, e.g. as follows:
-        &lt;schema . . .>
-         . . .
-         &lt;import namespace="http://www.w3.org/XML/1998/namespace"
-                    schemaLocation="http://www.w3.org/2001/xml.xsd"/>
-
-        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"/>
- 
-         will define a type which will schema-validate an instance
-         element with any of those attributes</xs:documentation>
- </xs:annotation>
-
- <xs:annotation>
-  <xs:documentation>In keeping with the XML Schema WG's standard versioning
-   policy, this schema document will persist at
-   http://www.w3.org/2007/08/xml.xsd.
-   At the date of issue it can also be found at
-   http://www.w3.org/2001/xml.xsd.
-   The schema document at that URI may however change in the future,
-   in order to remain compatible with the latest version of XML Schema
-   itself, or with the XML namespace itself.  In other words, if the XML
-   Schema or XML namespaces change, the version of this document at
-   http://www.w3.org/2001/xml.xsd will change
-   accordingly; the version at
-   http://www.w3.org/2007/08/xml.xsd will not change.
