I was assuming that if <xml:comment> were chosen to represent comments, 
its main (perhaps only) difference from other elements would be that it 
would be ignored for validation purposes - i.e it's not under schema 
control.

I've been interested to read people's views that comments should be 
allowed to contain "non-well-formed" content. It's a worthwhile point, 
but I don't find it compelling. The editing tool that creates the 
comment can always escape any markup within the comment.
