Problem with ELGG RSS FEEDS not showing as VALID RSS 1.0, 2.0 or Atom

I have noticed this issue for several months to a year now. I try as much as I can to submit most of the RSS Feed Streams to Popular RSS Feed Submission Search Engine sites and I have noticed that most or all Elgg RSS Feeds are showing Errors and are not passing any of the Submission Validation tests before they are even accepted or considered for submission.

When ever I test with my other sites that use WordPress those seem to pass 100% but my Elgg Main site seems to FAIL and will not be accepted to hundreds of Search Engines.

Now for SEO Purposes this can be an issue. For anyone else they would not see any problem and maybe not even care. I would like anyone's feed back on this and anyone who has had the same issue.

Thanks in advance.
