Short Fuse - Sub-second time reporting

We have a somewhat awkward expression of sub-seconds, using a duration to extend time expressions beyond seconds.

Would it break iCalendar compatibility if we used time as expressed in the w3c note?

http://www.w3.org/TR/NOTE-datetime

   Complete date plus hours, minutes, seconds and a decimal fraction of a second
      YYYY-MM-DDThh:mm:ss.sTZD (eg 1997-07-16T19:20:30.45+01:00

The note seems to make the following legal
      YYYY-MM-DDThh:mm:ss.sTZD (eg 1997-07-16T19:20:30.4567+01:00

We have discussed this before, but I do not recall
