Hi Jim,

Just a couple of minor issues, likely typos:

* <oa:Target> should be <oa:SpecificResource>. There's no such thing as <oa:Target> or <oa:Body>, as they're only true within the context of the annotation, and thus useless.
* And thus <oa:Body> should likely be <dctypes:Text>

* <oa:FragSelector> should be <oa:FragmentSelector>

But the structure and change for the new Composite look correct.

Thanks!

Rob

I wanted to pass the new annotation template by the list to make sure I'm getting everything right so I don't show one thing after attendees have been told something else.
