Specifying a Schema Location
XML documents can be linked with their schemas using the schemaLocation attribute. The schemaLocation attribute actually takes pairs of values, each pair consisting of a namespace name and a schema location, separated by white space. Example 8 is telling us that the processor can find declarations for elements and attributes in the http://example.org/emp namespace at the location emp.xsd. Because the schemaLocation attribute itself is in the http://www.w3.org/2001/XMLSchema-instance namespace, it is necessary to declare this namespace and map it to a prefix, usually xsi.
Example 8. Specifying a Schema Location
<emp:employee xmlns:emp="http://example.org/emp"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://example.org/emp emp.xsd"
hireDate="2001-04-02">
<number>557</number>
<status>FT</status>
</emp:employee>
