public class ExtensionHandlerJavaPackage extends ExtensionHandlerJava
xalan://partial.class.name xalan:// http://xml.apache.org/xalan/java (which is the same as xalan://)However, we do not enforce this. If the class name contains a a /, we only use the part to the right of the rightmost slash. In addition, we ignore any "class:" prefix. Provides functions to test a function's existence and call a function. Also provides functions to test an element's existence and call an element.
