I can't find any discussion about insufficient value range
for the types date, dateTime, gYear, gYearMonth and
duration, but I think  there is a gap: Infinity

Example:
I have an element "event" with the attributes dateTime,
duration and interval If I like to define the event as
starting at a point and continue for ever, i can't realize
this with the given nifty event element and no XSLT2/EXSLT
date function can handle infinities.

When there are infinite durations (and that's the real
life) it's also necessary to have infinite values for
the types date, dateTime, gYear, gYearMonth
  date + infinite duration = infinite date
