The documentation (within elements) below, is not normative, but rather highlights important aspects of the W3C Recommendation of which this is a part The simpleType element and all of its members are defined towards the end of this schema document simple type for the value of the 'namespace' attr of 'any' and 'anyAttribute' Value is ##any - - any non-conflicting WFXML/attribute at all ##other - - any non-conflicting WFXML/attribute from namespace other than targetNS ##local - - any unqualified non-conflicting WFXML/attribute one or - - any non-conflicting WFXML/attribute from more URI the listed namespaces references (space separated) ##targetNamespace or ##local may appear in the above list, to refer to the targetNamespace of the enclosing schema or an absent targetNamespace respectively notations for use within XML Schema schemas First the built-in primitive datatypes. These definitions are for information only, the real built-in definitions are magic. 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 Now the derived primitive types

About the XML namespace

This schema document describes the XML namespace, in a form suitable for import by other schema documents.

See http://www.w3.org/XML/1998/namespace.html and http://www.w3.org/TR/REC-xml for information about this namespace.

Note that local names in this namespace are intended to be defined only by the World Wide Web Consortium or its subgroups. The names currently defined in this namespace are listed below. They should not be used with conflicting semantics by any Working Group, specification, or document instance.

See further below in this document for more information about how to refer to this schema document from your own XSD schema documents and about the namespace-versioning policy governing this schema document .

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".

About this schema document

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: 

           <schema . . .>
            . . .
            <import namespace="http://www.w3.org/XML/1998/namespace"
                       schemaLocation="http://www.w3.org/2001/xml.xsd"/>

or 

            <import namespace="http://www.w3.org/XML/1998/namespace"
                       schemaLocation="http://www.w3.org/2009/01/xml.xsd"/>

Subsequently, qualified reference to any of the attributes or the group defined below will have the desired effect, e.g. 

           <type . . .>
            . . .
            <attributeGroup ref="xml:specialAttrs"/>

will define a type which will schema-validate an instance element with any of those attributes.

Versioning policy for this schema document

In keeping with the XML Schema WG's standard versioning policy, this schema document will persist at http://www.w3.org/2009/01/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/2009/01/xml.xsd will not change.

Previous dated (and unchanging) versions of this schema document are at:
