Credit where credit is due, W3C is just hosting a free instance of the
excellent feedvalidator open source software.

I'm not sure if I understand the spec exactly, but it seems to allow for
extensions, and will just ignore any attribute not in a known/local
namespace.

I see in the spec that these two attributes are defined for the
atom:link element, so I supposed they don't really fit into the
"undefined" attribute category?

I hope this helps, if not, I suspect you'll find more experts over on
the actual feedvalidator list:
