Atom 1.0 xml:base/URI funnies

[Tim Bray <Tim.Bray@xxxxxxx>]

I got an email last night from a well known syndication implementor  
pointing out an obvious bug in my Atom feed.  The feed's valid, but  
the stuff in <content> was full of relative URIs which were broken  
because I'd borked the xml:base.  So I went through the code and got  
the xml:base right and ruthlessly pruned all the pointers.  The feed  
looks a little weird and it's giving the (pre-alpha) validator a  
heartburn, but I sort of think it's right.  I also think it's good  
practice.  Check it out:
