Same way as CDATA sections. :-) DOM Core doesn't allow CDATA sections or  
PIs in HTML documents, but Opera allows them and it's not clear to me it  
makes sense to ban them from the DOM in HTML. (I'm planning to do a  
rewrite of DOM Core that doesn't have unnecessary differences between HTML  
and XML.)
