[QTI] duration data type

[Steve Lay]

Internally you will need to use a float to cover the fractional part 
issue.  I agree that there is a lack of clarify around the duration type 
(there was a clarification on the lexical representation at one point).

I have submitted an issue back to the consortium for resolution on this 
point.
