| I've just sent Andrew a module that parses and formats ISO 8601
| dates, at least as far as the W3C profile supports.  See
| http://www.w3.org/TR/NOTE-datetime for the profile.  We're planning
| on it going into the xml.utils package.

Great! Definitely a highly useful piece for the cabal. I can think of
several different places where this might be useful in my current XML
stuff.
