10139N/A See http://www.w3.org/XML/1998/namespace.html and

10139N/A http://www.w3.org/TR/REC-xml for information about this namespace.

10139N/A

10139N/A This schema document describes the XML namespace, in a form

10139N/A suitable for import by other schema documents.

10139N/A

15291N/A Note that local names in this namespace are intended to be defined

10139N/A only by the World Wide Web Consortium or its subgroups. The

10615N/A following names are currently defined in this namespace and should

15301N/A not be used with conflicting semantics by any Working Group,

16382N/A specification, or document instance:

10139N/A

10139N/A base (as an attribute name): denotes an attribute whose value

10139N/A provides a URI to be used as the base for interpreting any

10139N/A relative URIs in the scope of the element on which it

16155N/A appears; its value is inherited. This name is reserved

10794N/A by virtue of its definition in the XML Base specification.

10139N/A

10794N/A id (as an attribute name): denotes an attribute whose value

12773N/A should be interpreted as if declared to be of type ID.

12773N/A The xml:id specification is not yet a W3C Recommendation,

12773N/A but this attribute is included here to facilitate experimentation

10794N/A with the mechanisms it proposes. Note that it is _not_ included

10139N/A in the specialAttrs attribute group.

10640N/A

10139N/A lang (as an attribute name): denotes an attribute whose value

10640N/A is a language code for the natural language of the content of

10139N/A any element; its value is inherited. This name is reserved

10820N/A by virtue of its definition in the XML specification.

16105N/A

10820N/A space (as an attribute name): denotes an attribute whose

16105N/A value is a keyword indicating what whitespace processing

10820N/A discipline is intended for the content of the element; its

16347N/A value is inherited. This name is reserved by virtue of its

16347N/A definition in the XML specification.

10861N/A

13306N/A Father (in any context at all): denotes Jon Bosak, the chair of

12139N/A the original XML Working Group. This name is reserved by

12139N/A the following decision of the W3C XML Plenary and

13379N/A XML Coordination groups:

13379N/A

15219N/A In appreciation for his vision, leadership and dedication

14420N/A the W3C XML Plenary on this 10th day of February, 2000

14503N/A reserves for Jon Bosak in perpetuity the XML name

14503N/A xml:Father

10139N/A <xs:annotation>

10139N/A <xs:documentation>This schema defines attributes and an attribute group

10139N/A suitable for use by

10139N/A schemas wishing to allow xml:base, xml:lang, xml:space or xml:id

10139N/A attributes on elements they define.

10139N/A

10139N/A To enable this, such a schema must import this schema

10139N/A for the XML namespace, e.g. as follows:

10139N/A &lt;schema . . .&gt;

10139N/A . . .

10139N/A &lt;import namespace="http://www.w3.org/XML/1998/namespace"

10139N/A schemaLocation="http://www.w3.org/2001/xml.xsd"/&gt;

10139N/A

10139N/A Subsequently, qualified reference to any of the attributes

10139N/A or the group defined below will have the desired effect, e.g.

10139N/A

10139N/A &lt;type . . .&gt;

10139N/A . . .

10139N/A &lt;attributeGroup ref="xml:specialAttrs"/&gt;

10139N/A

10139N/A will define a type which will schema-validate an instance

10139N/A element with any of those attributes</xs:documentation>

10139N/A <xs:annotation>

10139N/A <xs:documentation>In keeping with the XML Schema WG's standard versioning

10139N/A policy, this schema document will persist at

10139N/A http://www.w3.org/2005/08/xml.xsd.

10139N/A At the date of issue it can also be found at

10139N/A http://www.w3.org/2001/xml.xsd.

10139N/A The schema document at that URI may however change in the future,

10139N/A in order to remain compatible with the latest version of XML Schema

10139N/A itself, or with the XML namespace itself. In other words, if the XML

10139N/A Schema or XML namespaces change, the version of this document at

10139N/A http://www.w3.org/2001/xml.xsd will change

10139N/A accordingly; the version at

10139N/A http://www.w3.org/2005/08/xml.xsd will not change.
