Sadly none of the arguments in any direction right now are particularly 
persuasive.

I'm not really convinced that the data that the above proposed survey 
might collect would actually help, since it doesn't tell us the what was 
intended by the author. You'd be surprised at how often people use 
ampersands in text in ways that have nothing to do with entities but in 
ways which could get interpreted as entities.

The number of occurences of "r&eacutesum?? "is at least two (the two hits
I looked at both worked in IE and did not in Firefox).


Am I correct in assuming that you would like the spec changed? What would 
you like the spec changed to, exactly?
