The customization required for this extra feed with respect the existing feed are:
1. The feed URL should be in the current day date format: dd-mm-yy.xml
2. The feed should have the full content of the posts ( against the excerpts only in the other feed file)
3. All the posts should be added in the feed ( against the limited numbers set in the other feed file )
In other words I need an additional identical feed generated using current date as the URL, listing full contents of the whole posts on the WP.
