en WordPress.com Forums › Support Feeds with DTDs Author Posts January 30, 2008 at 4:09 pm #186957 snpnmnmiMember I’m new to feeds and this is an message that appears over the feed info when I try to read it: Feeds with DTDs are not supported What is a DTD, please… and do I need to do something to resolve this… is it a problem? Thanks!
