[whatwg] RDFa statement consistency

WHATWG cannot purge existing ignored elements and properties but it can try
avoiding adding new ones.
Besides, I wonder if the promoter of the DFN element make it clear that he
expected it to be ignored by the browser, as is the case with RDFa.

The HTML 5 spec already includes the many features which browsers  
currently (mostly) ignore - the <meta> tag, the "type" attribute on  
most links and so on. The fact that HTML includes a <dfn> element  
doesn't mean that every browser has to have a built in dictionary for  
storing all the definitions people collect on the web, but the  
element is there for those people who want to use it. Browsers  
*could* do something useful with <dfn> if they liked, but none so far  
seem to have done so.
