Inconsistency in Blogger's Atom Generator

I found that the Atom generated by Blogger is not vert consistence. Sometimes the < and > signs are shown as &lt; and &gt; while sometimes are still < and >.

Weird, isn't it? I don't even know how to trigger it... -__-|||

See http://minghong.blogspot.com/atom.xml if you don't know what I'm talking about.

By the way, if you use some standard-compliant browsers like Mozilla to view that XML, you'll notice that the CSS style is not quite consistence either.
