This schema document provides attribute declarations andattribute group, complex type and simple type definitions which can be used inthe construction of user schemas to define the structure of particular linkingconstructs, e.g.<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xl="http://www.w3.org/1999/xlink"> <xs:import namespace="http://www.w3.org/1999/xlink" location="http://www.w3.org/1999/xlink.xsd"> <xs:element name="mySimple"> <xs:complexType> ... <xs:attributeGroup ref="xl:simpleAttrs"/> ... </xs:complexType> </xs:element> ...</xs:schema>
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
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"/> 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
In keeping with the XML Schema WG's standard versioningpolicy, this schema document will persist athttp://www.w3.org/2007/08/xml.xsd.At the date of issue it can also be found athttp://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 Schemaitself, or with the XML namespace itself. In other words, if the XMLSchema or XML namespaces change, the version of this document athttp://www.w3.org/2001/xml.xsd will changeaccordingly; the version athttp://www.w3.org/2007/08/xml.xsd will not change.
