I agree with Larry -- the charter *clearly* doesn't ask for RDFa or 
(similar extensions) to be added, but for an extension mechanism that 
allows to add those.

"The HTML WG is encouraged to provide a mechanism to permit 
independently developed vocabularies such as Internationalization Tag 
Set (ITS), Ruby, and RDFa to be mixed into HTML documents. Whether this 
occurs through the extensibility mechanism of XML, whether it is also 
allowed in the classic HTML serialization, and whether it uses the DTD 
and Schema modularization techniques, is for the HTML WG to determine."

And no, this isn't *twisting* the charter (-> 
<http://krijnhoetmer.nl/irc-logs/whatwg/20100113#l-552>), it's *reading* it.

That being said, I'd like the W3C to work on metadata extensions for 
HTML, and do not care particularly where it happens. We already 
published RDFa-in-HTML, so I wouldn't object to Microdata as well, as 
long as it remains clear that it has exactly the same status with 
respect to document validity.

Best regards, Julian
