/>Add specified JavaHelp jar (Java™ Archive) to XXE online help. This JavaHelp jar must contain file /help/jhelpset.hs describing its help set.
Example:
<help location="docbook_help.jar" />
Such JavaHelp jars can be localized. If, for the previous example, the language of current locale if fr (variant such as CA in fr_CA is ignored by XXE), XXE will try to load docbook_help_fr.jar and if this fails, it will attempt to load docbook_help.jar.
