# saxon:script

The `saxon:script` element is a top-level element. 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, `xalan:script`).

The attributes for `saxon:script` are the same as the attributes of the `xsl:script` element defined in the (now withdrawn) XSLT 1.1 working draft.

The `language` 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 `saxon:script` element.

The `implements-prefix` 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.

The `src` 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.

The `archive` 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.
