DESCRIPTION
The libexslt library is used to provide extensions toXSLT
functions. These extensions come from the
EXSLT
project <www.exslt.org>
USAGE
To make use of these functions inXSLT
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
