Well, if ISSUE-41 is how the HTML-WG is addressing the
extensibility mechanism in the charter, then what again
is the rationale for adding microdata?

I think that in broad terms you are correct that we should consider  
extension mechanisms more generally, and see if any broadly powerful  
ones need to be added. I believe that is covered under ISSUE-41  
decentralized-extensibility, where we have had much discussion and  
soon will need to convert our thinking into concrete proposals.

I'm not sure I agree entirely with all of your specific comments, but  
I'm thinking I will save that commentary for the ISSUE-41 discussion.

Regards,
Maciej
