If a plugin adds some content at the loop_start point of the WordPress page load it appears that this content is being added to the RSS feed output. Is this the proper action? If so it is not stated anywhere that this would be the result of placing something at this point.
I have some plugins that use the loop_start tag to display information to the visitor above the posts area, but this info is being added to the RSS feed listing as HTML fields. Most RSS readers will ignore this text (since it does not correspond to the proper XML fields), but it's certainly annoying and not something I'd like to have happen. Is there a way to prevent this?
You can see this in action by going to my development website http://www.awsom.org and clicking my RSS feed link, you'll then see from the page source view that my drop down archive is added to the RSS stream.
Is there some kind of filter I could use to prevent this from being output?
