My online conversation with Stephen Downes regarding the implications of hyperlinks within RSS descriptions continues. He says:
“I think the principle is something like this: the rule is that you can't place markup in your description element, but XML allows it (some say, with things like CDATA, encourages it) and most aggregators can handle it, but because it's the rule, you have no ground for complaint if someone strips it out in order to display your feed. Of course, none of this is formalized anywhere.”
