It seems to be it should be confirming to serve content that uses one  
or more "other applicable specifications" extensions. Is that  
consistent with what the MIME registration says? If not, we'd better  
fix it, or not only @profile but also RDFa and Microdata will be  
nonconforming to send in text/html. I assume this is not what we want.
