| This schema defines attributes and an attribute group suitable | |
| for use by schemas wishing to allow <code>xml:base</code>, | |
| <code>xml:lang</code>, <code>xml:space</code> or | |
| <code>xml:id</code> attributes on elements they define. | |
| </p> | |
| <p> | |
| To enable this, such a schema must import this schema for | |
| the XML namespace, e.g. as follows: | |
| </p> | |
| <pre> | |
| <schema . . .> | |
| . . . | |
| <import namespace="http://www.w3.org/XML/1998/namespace" | |
| schemaLocation="http://www.w3.org/2001/xml.xsd"/> | |
| </pre> | |
| <p> | |
| or | |
| </p> | |
| <pre> | |
| <import namespace="http://www.w3.org/XML/1998/namespace" | |
| schemaLocation="http://www.w3.org/2009/01/xml.xsd"/> | |
| </pre> | |
| <p> | |
| Subsequently, qualified reference to any of the attributes or the | |
| group defined below will have the desired effect, e.g. | |
| </p> | |
| <pre> | |
| <type . . .> | |
| . . . | |
| <attributeGroup ref="xml:specialAttrs"/> | |
| </pre> | |
| <p> | |
| will define a type which will schema-validate an instance element | |
| with any of those attributes. | |
