| Represents an extension namespace for XPath that handles java classes. | |
| It is recommended that the class URI be of the form: | |
| <pre> | |
| xalan://fully.qualified.class.name | |
| </pre> | |
| 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. | |
