+   * Returns the canonical name of this class, as defined by section
+   * 6.7 of the Java language specification.  Each package, top-level class,
+   * top-level interface and primitive type has a canonical name.  A member
+   * class has a canonical name, if its parent class has one.  Likewise,
+   * an array type has a canonical name, if its component type does.
+   * Local or anonymous classes do not have canonical names.
+   * </p>
+   * <p>
+   * The canonical name for top-level classes, top-level interfaces and
+   * primitive types is always the same as the fully-qualified name.
+   * For array types, the canonical name is the canonical name of its
+   * component type with `[]' appended.  
+   * </p>
+   * <p>
+   * The canonical name of a member class always refers to the place where
+   * the class was defined, and is composed of the canonical name of the
+   * defining class and the simple name of the member class, joined by `.'.
+   *  For example, if a <code>Person</code> class has an inner class,
+   * <code>M</code>, then both its fully-qualified name and canonical name
+   * is <code>Person.M</code>.  A subclass, <code>Staff</code>, of
+   * <code>Person</code> refers to the same inner class by the fully-qualified
+   * name of <code>Staff.M</code>, but its canonical name is still
+   * <code>Person.M</code>.

+   * Where no canonical name is present, <code>null</code> is returned.
