comment: duration description example seems incomplete

In
Time Ontology in OWL 
W3C Editor's Draft 18 May 2006
http://www.isi.edu/~pan/SWBP/time-ontology-note/time-ontology-note-3rdEd.html

I see this example...

[[
For example, duration of 15 days, 5 hours and 20 seconds is represented
in iCalendar as P15DT5H0M20S, which can be represented in the time
ontology as:

:duration
      a       :DurationDescription ;
      :seconds 20 ;
      :hours 5 ;
      :days 15 .

]]

That description needs all the other fields filled in, no? Otherwise,
it could be that :duration :years 2, which is very different
from P15DT5H0M20S.

Also, that example suggests that :duration is in the same
namespace as :seconds, :hours, and :days. I suggest you
distinguish terms from example data from terms in the time ontology.
