Since I use mostly aggregated feed from sponsors blogs, most of my posts contain permalinks, comment links, etc. that have affiliate codes at the end of the URL.
If you are using WordPress and these links contain an ampersand you may have validation issues with your own RSS feeds.
I have a solution for anyone that's interested. It involves inserting a little PHP coding in just the right place in several WP library functions.
If anyone is interested I'll type up a more detailed list of the files and functions to edit.
Special thanks to TPat for noticing that there even was a problem.
