Invalid Comments RSS Feed

Version 2.2.2. I just noticed my comments feed does not validate. I looked at the xml for both the comments feed as well as the main feed. The main feed uses the dc:creator tag around my public name which validates. However, the comments feed uses the author tag around my public name. Apparently, the author tag needs to contain a valid email address to validate.

I deactivated plugins with no luck getting the comments feed to validate. Before I submit a ticket on trac, can anyone replicate this? Thanks.
