+ * following parameters:
+ * <ul>
+ * <li><base href=<b>url</b>>
+ * <li>< ... codebase=<b>url</b> ... >
+ * </ul>
+ *
+ * The following parameters are not accounted for either (as the textbooks

+ * <li><td background=<b>url</b> ... >

+ * </ul>
+ *
+ * Due to the recent refactoring of this class, these might not be as difficult
+ * as they once might have been.

+ * Finally, this class does not process <b>Style Sheets</b> either.
