   The  libexslt  library is used to provide extensions to XSLT functions.
   These extensions come from the EXSLT project <>


   To make use of these functions in XSLT the appropriate  namespace  must
   be  defined  on the xsl:stylesheet element.  To enable support for them
   in libxslt(3) you must call the appropriate functions  (listed  in  the
   SYNOPSIS  section)  to  register the extensions.  The xslt-config shell
   script can be used to obtain the necessary flags for the  pre-processor
   and linker.  The supported extensions are:


   See for a description.

   node-set()            convert the given RTF into a node-set.

   object-type()         returns the type of the given argument.

   highest()             returns  the nodes in the node-set whose value is
                         the maximum value for the node-set.
