   Notice that stopping and then restarting XMLmind XSL Server was not needed in order to customize a stock conversion.

   Remember XMLmind XSL Utility has other uses related to XMLmind XSL Server. It allows to specify a custom font map for Apache FOP. For example, use Verdana instead of the sans-serif logical font family. This is done very easily by clicking Preferences and then selecting XSL-FO Processor|FOP. See XMLmind XSL Utility - Online Help, FOP preferences . However in such case, you'll have to stop and then restart XMLmind XSL Server. It allows to specify helpers applications, for example, the location of the HTML Help compiler, hhc.exe, which is needed to convert a DITA document to HTML Help (.chm file). This is done very easily by clicking Preferences and then selecting Helper Applications. See XMLmind XSL Utility - Online Help, Helper applications preferences . When this is the case, you do not need to stop and then restart XMLmind XSL Server.
