The difference is when a conformance checker alerts an author about  
an error. Since the omission of the semicolon is potentially  
confusing, it makes sense to make the omission non-conforming so that  
conformance checkers alert authors who have omitted the semicolon  
inadvertently (e.g. by pasting a URL that contains a query string  
part that looks like an entity reference). This way, unintentional  
omissions are caught. After all, deliberate omissions are probably  
only done by a small group of language lawyers.
