Our draft is not about how you represent timezone (UTC offsets) in 
date-time values (which is mostly what that w3.org reference talks about).

Our draft is about representing timezone definitions (standard time 
offsets, daylight saving time rules, how they varying over time, etc) in 
XML. This is akin to iCalendar's VTIMEZONE data or zoneinfo data found on 
Unix systems (and in a more "raw" form the Olson timezone database). One of 
the primary goals for this is to support exchange of timezone definitions 
between system via a timezone service protocol 
(draft-douglass-timezone-service - another draft we submitted a short while 
ago).

I believe this is clear in our draft, though admittedly the abstract may 
not convey that in as much detail as it should (and I will endeavor to beef 
up the abstract to clarify this).
