+ * A base class for writing XPath functions that replaces much of the

+ * <ol>
+ * <li> Initialization: the subclass method {@link #init} is invoked.
+ * <li> Input: for each argument, the type-appropriate {@link #processArg}
+ * method is called.
+ * <li> Completion: the subclass method {@link #getResult} is invoked, and
+ * its return value is returned from {@link #evaluate}.
+ * </ol>
+ * <p>
+ * Subclasses define their name, namespace, and the number of arguments
+ * they accept (which may be undefined).
+ * <p>
+ * To support thread safety, subclasses are expected to make use of a helper
+ * object that holds intermediate results. The helper object is created by
+ * <code>init()</code>, is an argument to and return from <code>processArg()
+ * </code>, and is an argument to <code>getResult()</code>. Subclasses are
+ * parameterized with the helper object type, and the default behavior of
+ * <code>getResult()</code> is to return the helper (this makes life easier
+ * for a function that takes zero or one arguments).
+ * <p>
+ * <em>Note:</em> in JDK 1.5, DOM objects implement both <code>Node</code>
+ * and <code>NodeList</code>. While this means that <code>processArg(Node)
+ * </code> would never be called as part of the normal dispatch loop (unless
+ * the implementation changes), it <em>is</em> called as part of the default
+ * behavior of <code>processArg(NodeList)</code>, and is given the first
+ * element in the list.
