Feed RSS problem

Hello,

The feed generated by my blog is with problem. The Feedvalidator.org detect this error:

line 12, column 93: Self reference doesn’t match document location

… rel=”self” type=”application/rss+xml” />

This is the Line 12:

<atom:link href=”feed-address” rel=”self” type=”application/rss+xml” />

But I don’t know where correct this rel=”self” option and I don’t know what is the correct value for this.

How resolv this?
