NAME
libexslt - extension library for XSLT
DESCRIPTION
The libexslt library is used to provide extensions to XSLT functions.
These extensions come from the EXSLT project (http://www.exslt.org/)
CALLING
To make use of these functions XSLT, these need to be declared with the
proper name space

ber.
seconds() returns the number of seconds specified by
the argument string.
add() returns the date/time resulting from
adding a duration to a date/time.
add-duration() returns the duration resulting from adding
two given durations together.
difference() returns the duration between the first
date and the second date.
duration() returns a duration string that represents
the given number of seconds since
