As usual, a lengthy agenda, but we will focus the discussion on:
   - all the ACTIONS you would have _done_ ;-)
   - the test cases for the temporal dimension and how we handle errors, 
following last week discussion, proposal of TC by Silvia and entered in 
the tool by Michael.
Best regards.

Dom: 
http://lists.w3.org/Archives/Public/public-media-fragment/2010Jan/0093.html
* Correct the NPT scheme (drop the 's') and point to 
http://www.w3.org/TR/NOTE-datetime

* ACTION-126: Yves to follow up on error in ABFN for npt

3.2 Protocol for URI fragment Resolution in HTTP:
* ACTION-123: Yves to come up with ABNF for header syntax

3.3 Rendering of Media Fragments URI in UA:
* ACTION-135: Davy, Erik to extend section 5 regarding spatial and track 
dimension
* ACTION-137: Jack to check that 5.1.4 is implementable using the protocol
* ACTION-141: Conrad to add a paragraph in the section 5.2.1 that 
further clarify the role of the UA for rendering a media fragment
* ISSUE-5 [Jack]: Handling spatial cropping requires information at

6. IMPLEMENTATION:
