Organized first draft of Use Case and Requirements Document

I've now taken the original collated list of 70 use cases and requirements from http://lists.w3.org/Archives/Public/public-xg-htmlspeech/2010Sep/0051.html and created a first draft of a document that combines like use cases and requirements and organizes the remaining 15 use cases and 34 requirements into different related sections.  I've also (generously) linked the requirements back to the use cases that support them.  For contribution I also took the style of the VBWG (everyone listed in the editors section, not a separate editors and authors section), appologies in advance if I missed someone, I took the people who were linked in the earlier collation above (and I wasn't sure what the organization was for the two people who aren't members of the XG).



As always, if there are some use cases or requirements that could be made more clear or added, that would be great.



For a next step I've asked Dan to consider running a poll that will help us prioritize the use cases and requirements so we can start by focusing the discussion on the use cases and requirements that have the highest priority.
