DESCRIPTION

   The  libexslt  library is used to provide extensions to XSLT functions.
   These extensions come from the EXSLT project <http://www.exslt.org/>

USAGE

   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:

   COMMON
