I was under the impression that for images that convey no meaning whatsoever
it was best to include an empty alt text thus alt=""

The image in question is a horizontal line in Corporate colours required by
our Council design guidelines (believe me, if I had my way it'd just be a
<hr>)and as such conveys nothing useful to a user (sighted or otherwise). 

What would you suggest as a suitable piece of text? maybe alt="meaningless
image, please ignore"?

thanks
Julian
