+ * <li>mergefile
+ * <li>smart
+ * <li>dependent

+ * <P>
+ * xalan is only called if either the outfile is older than the infile or the stylesheet
+ * or the outfile doesn't exist.
+ * <P>
+ * <p>dependent defaults to 'none'. Other possible values: a comma delimited list of file names
+ * which date is checked against the output file. This way you can name files which, if
+ * they have been modified, initiate a restart of the xslt process, like external entities etc.
+ * <p>
+ * The mergefile parameter causes this task to merge the contents of the specified file into the infile at the end. This is used for the font character mapping generation because the keys() xslt function doesn't work on an external document.
