I just merged the non-obvious ones into the text and removed the obvious 
ones. (Saying "Con: Proposal may be more complex" isn't helpful.) I don't 
think I removed any non-trivial ones, which ones did you have in mind? My 
apologies if I did remove anything non-trivial.

The section said "Choice of format: There are already several metadata 
formats. In the future there may be more", and that's not a requirement. A 
requirement is something that a proposal can be evaluated against. This 
isn't something that can be evaluated against, it's just an axis.

It's like "choice of height" as opposed to "must be at least 6ft tall" 
when discussing requirements for a shed.

HTML5 already has something that satisfies those requirements (the class 
attribute) so clearly (assuming HTML5 as written today isn't enough) there 
are more requirements than that, at least from the RDFa community.
