Jessica,

I'm going to be late for the NDRSC telecon, and will *not* make the DON 
XML AT2 telecon.

For the NDR telecon, I do have a few comments which I hope you could 
relate for me.

In the NDR document, Section 6, Date and Time:

     6.1.1 The XML Schema recommendation allows three different 
representations of date/time. Should we restrict the use to just one? I 
would recommend the canonical form (all dates/time are Zulu Time (GMT), 
indicated by a trailing z); this would allow for more efficient processing.

     6.1.2 Might we want to disallow truncated form, unless the time 
component being truncated is at the trailing end? For example, a 
duration of 3 years, 11 months, 4 days and 15 minutes can be represented 
in the following ways:

         1) P3Y11M4DT15M
         2) P3Y11M4DT0H15M  (I recommend this one; again, to facillitate 
processing.)
         3) P3Y11M4DT0H15M0S

I hope to make it for the last hour or so of the NDRSC telecon, but you 
know how meetings can go...

Thanks,
Mike Grimley
