That's problematic, because allowing it as a conforming entity  
reference does not add any expressiveness to the language but makes  
conformance checking less useful as an authoring aid (because '  
fails in IE and such failure could be trivially avoided).

I think I'm going to emit a warning even if ' is conforming.

I am uncomfortable with <, >, &, " and © on  
aesthetic grounds, but at least they work interoperably.

By the way, the handling of these entities is currently the only  
special case in my parser that varies depending on the doctype (HTML  
4.01 vs. HTML5).
