An anonymous reader writes "In the standard definition of RSS 0.91, there are a couple of lines referring to 'DOCTYPE' and referencing a 'dtd' spec hosted on Netscape's website. According to an article on DeviceForge.com quite a few RSS feeds around the web probably stopped working properly over the past few weeks because Netscape recently stopped hosting the critical rss-0.91.dtd file.

has been offered by a Netscape employee.
