Hi
I have tried to write a feed (see attached zip file).
However when I try to validate it, I get the following errors:
This is my first time trying to create a feed and I didn’t do that well 
This feed does not validate.
line 13, column 0: Undefined item element: id (3 occurrences) [help]
<id>14</id>
line 14, column 0: Undefined item element: gender (3 occurrences) [help]
<gender>M</gender>
line 15, column 0: Undefined item element: fname (3 occurrences) [help]
<fname>Truck</fname>
line 43, column 0: Missing channel element: description [help]

</channel>
In addition, interoperability with the widest range of feed readers could be improved by implementing the following recommendations.
Feeds should not be served with the “text/html” media type [help]
your feed appears to be encoded as “UTF-8”, but your server is reporting “US-ASCII” [help]
line 43, column 0: Missing atom:link with rel=“self” [help]
