Description should be parsed as a summary

[teddychoi]

Now, content:encoded and description elements in RSS1.0 and RSS2.0 are both treated as the content of the feed.
So if the item contains both content:encoded and description, the element that displayed later fills the content, and the other is dismissed.
But in the real world, description is usually treated as the summary of the content, thus dismissing problem can be solved as put the description in the summary element.
