http://lists.w3.org/Archives/Public/public-media-fragment/2009Nov/0023.html 

"I'd also like to point out that the ABNF for NPT does not match
RFC2326. It allows there to be 0 or more digits following the decimal
point, while the MF ABNF allows 1 or more digits."

* Davy's strawman implementation using ROE:
http://lists.w3.org/Archives/Public/public-media-fragment/2009Nov/0014.html 
* Silvia's blog post:
http://blog.gingertech.net/2009/11/25/manifests-exposing-structure-of-a-comp
osite-media-resource/ 
* Jack's proposal to write up that we should distinguish the mechanism (ROE,
MPEG-21) vs the semantics

2.5 Handling of 'Track' and 'ID':
Conrad's proposal (Fragment header):
http://www.w3.org/2008/WebVideo/Fragments/wiki/Server-parsed_Fragments

* ACTION-34: Jack to look at python-url library to see whether he could
implement the logic on client side

could be implemented on client side
* ACTION-70: Jack to commit in CVS (code directory) his python code doing
the parsing on client side of the media fragment
