      <description>Weekly gardening tips from Tom</description> 
      <generator>Tom's Feed Generator, v0.01b</generator>
      <ttl>1440</ttl>
  Notice the content XML namespace, this allows us to include the entire post, not just a summary within the feed. I’ve also included the TTL declaration in this script, aggregators should notice this and refresh the feed only once a week. You could also look into the skipDays and skipHours elements to further define this more clearly.
