Hi Davy, Silvia,

About merging the summary table of
http://www.w3.org/2008/WebVideo/Fragments/wiki/HTTP_Fragment_Caches#Media_format_classification 
 into 
http://www.w3.org/2008/WebVideo/Fragments/wiki/Types_of_Fragment_Addressing

Yes, Davy did a great job summarising all the important media formats
and the kind of fragments that can be expected in each format according
to caching abilities. I noticed it yesterday so I added the link at the
bottom of the 'Types of Media Fragment Addressing' wikipage.

Would it be useful to have a table that shows what Use Case apply to
what Media Format?
Would it be useful to have examples of Media Fragment URI that could
apply next to each Media Format?

Regards,
Guillaume
