You can (and I think we have) run into the same kind of issues with order  
of HTTP headers, HTTP header casing, etc. HTTP isn't very conservative in  
what clients have to do, while it probably should be given that there are  
only so many clients versus many many servers. Although not protocols, we  
learned the same lessons with e.g. CSS, the DOM, and HTML. (Also known as  
Postel's law.)
