minor edits based on Vad's feedback

And those minor edits are:

* Clarified that Duration granularity values are Java longs
* Link to Wikipedia ISO8601 page for those who'd like to read up on that standard to make sense of some of the examples and how to create their own
What do you suggest should be in the docs to specify allowable value? Is it
good enough to state that it's an integer and assume that no one is likely
to exceed the bounds?
