In particular, it seems that neither FF2 nor FF3 follow these rules with 
respect to ignoring text/plain in certain situations (test cases 008, 
009, 010 in 
<http://www.hixie.ch/tests/adhoc/http/content-type/sniffing/>). So I'd 
really like to understand why this can be considered a "MUST" level 
requirement when we have proof that popular browsers can get away with 
*not* ignoring the Content-Type header here.
