It is used to define an implementation for an extension function that will be used by Saxon. With other processors, a different implementation of the same function can be selected, using mechanisms defined by that processor (for example, <code>xalan:script</code>).</p> <p>The attributes for <code>saxon:script</code> are the same as the attributes of the <code>xsl:script</code> element defined in the (now withdrawn) XSLT 1.1 working draft.</p> <p>The <code>language</code> attribute is mandatory, and must take the value "java". The values "javascript", "ecmascript", or a QName are also permitted, but in this case Saxon ignores the <code>saxon:script</code> element.</p> <p>The <code>implements-prefix</code> attribute is mandatory, its value must be a namespace prefix that maps to the same namespace URI as the prefix used in the extension function call.</p> <p>The <code>src</code> attribute is mandatory for language="java", its value must take the form "java:fully.qualified.class.Name", for example "java:java.util.Date". It defines the class containing the implementation of extension functions that use this prefix.</p> <p>The <code>archive</code> attribute is optional, its value is a space-separated list of URLs of folders or JAR files that will be searched to find the named class. If the attribute is omitted, the class is sought on the classpath.</p> <table width="100%"> <tr> <td> <p align="right"><a class="nav" href="try-instr.xml">Next</a></p> </td> </tr> </table> </body> </html>
