| 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. |
