Six months after the Google News RSS feed validation issues were reported in Google News Help forums, Google has fixed the issue.
The first report came in a Google News Help thread on August 7, 2009. Yesterday, on February 8, 2010, Inbal from Google, said the issue was resolved. Inbal said:
I am not sure why it took over 6 months to fix, but now it is resolved.
