Hi,

I am in need of validating a programatically created RSS file. With that I coded the following XSD, but all validators I used say schema is invalid.

How can I confirm its actual validity and what are other ways to validate a RSS file.

The above XSD is invalid.

But following Schema for RSS2.0 is great. I place it here because others may found it useful.
