I agree that the documentation that we've provided for the EXSLT
functions leaves something to be desired. I would encourage you to open a
bug report requesting that the documentation be improved.

I believe that the argument to date:date, et al. is an actual date,
time or date-time value which is to be formatted as CCYY-MM-DD - the
argument is not supposed to be a format string such as 'YY-MM-DD'. If no
argument is specified, the current date and time are used. If the
argument can't be interpreted as a date or time value, the function
returns an empty string, which explains the behaviour you observed; EXSLT
requires that. Most of the other date/time functions follow the same
form: the functions format the input date or time value using a fixed
format; if no argument is specified, the current date/time is used; if the
input string is invalid, the function returns an empty string.
I believe you need to use the date:format-date function to specify
your own format. For example, "date:format-date('2005-11-07',
'yy-mm-dd')".
I hope that helps.
Thanks,
Henry
