In addition, interoperability with the widest range of feed readers could be improved by implementing the following recommendations.

    line 42, column 123: title should not contain HTML: i (4 occurrences) [help]

        ... ; status still Open with 2 other changes</title>
                                                     ^

    line 189, column 2: Missing atom:link with rel="self" [help]

          </channel>
          ^

Clearly the one that should be fixed is the "invalid email one". Following their explanation should not be hard - whenever we get only a user name (without domain), it is sufficient to append "@example.com" to it. This leaves us with a warning about lack of real name, which we can ignore.

I do not like the idea of using fake email addresses. Since "author" field is optional, can we just replace it with dc:creator.

Note: dc:creator requires adding namespace to rss element:

<rss xmlns:dc="http://purl.org/dc/elements/1.1/">

I agree. Using dc:creator is both better and easier.
