On the contrary, it was heavily influenced by the experiences of all the 
above and more.

If there are specific use cases I somehow missed when going through the 
hundreds of e-mails on this topic, please bring them up, as I would be 
glad to make sure all use cases have been addressed.

As a reminder, the use cases I examined (including those that I explicitly 
couldn't find solutions for) are all listed in the e-mails listed here:

Indeed; I examined all the existing solutions that I could find closely as 
the first step (well, the second step, after collecting use cases). I 
didn't go through all of them one by one in the e-mail, but I did 
explicitly examine Microformats and RDFa:

I believe that the above e-mails include ample technical justification for 
these decisions.

The cost to implementations for the existing proposed solutions was in 
fact one of the big factors in developing a new proposal.
