Modified: java/xdocs/sources/xalan extensions.xml overview.xml Log: Add paragraph about XSLT extensions in general per suggestion from John Gentilin <[EMAIL PROTECTED]>.

For example, you can use the Redirect extension elements shipped with &xslt4j; to redirect portions of your transformation output to one or more files. Extension elements may contain attributes, text nodes, other elements, basically any valid XML. Extension elements may perform quite sophisticated actions, given that the extension routine (the implementation) has direct access to the XSLT processor context object and to the element. In many cases the implementation returns void or null; if it does return a value, that value is placed in the transformation result tree.</p> -<p><em>Extension functions</em>You can think of extension functions as extending the core library of functions that XPath provides. An extension function passes arguments to the extension implementation and returns a value. You can use extension functions to return values that XSLT can interact with directly (node-set, result tree fragment, string, boolean, and number) as well as values (of any type) that you pass in turn to other extension functions. Extension functions written in Java can also access certain items in the XSLT execution environment through an <jump href="apidocs/org/apache/xalan/extensions/ExpressionContext.html">ExpressionContext</jump> interface.</p> +<p><em>Extension functions</em> You can think of extension functions as extending the core library of functions that XPath provides.

BSF allows an application to take advantage of scripting while being independent of any specific scripting language. To date, we have tested extensions implemented in JavaScript.
