RSS: Effects of using custom tags

[GUIR]

Hi,

Could someone please let me know the validity of using custom XML tags in an RSS documents, other than standard RSS tags.

Thanks and Best Regards

That's going to depend upon just what type of RSS you are writing. The ATOM feed is intended to be extensible. Which is to say that you simply give your special elements their own namespace and aggregators are supposed to ignore them. See http://atompub.org/rfc4287.html .
