RSS Hygene
At the present time, neither scripting.com's nor aaronsw's RSS feeds are well formed XML 1.0.
Update: scripting.com's RSS feed is once again well formed. Thanks Dave!
Update: Aaron's RSS feed is once again well formed, but Aaron questions whether or not such encoding problems affect the validity of the document. Perhaps this will help settle the issue: I have tried such documents against the Python xml.sax, Xerces, and the msxml parsers, and each refuse to parse documents containing such errors.
