[lxml-dev] atom model

[Ian Bicking]

After writing a object model for Atom that serialized to and parsed from 
XML, I realized Atom and its XML representation really shouldn't be 
separated, so I created some custom elements to make it a bit easier to 
handle, while still using the XML as the sole source of information.

I'm a little unsure what to do about the namespaces.  Everything is in a 
namespace, but it's tedious to put in everywhere.  I've put in some 
little helper methods internally, and mostly you don't need to use the 
namespace globally, but I'm unsure about it all.  I've created an 
Element() function that automatically adds the namespace if no namespace 
is given; helps a little I guess.

The standard ways of creating elements is a bit tedious, really.  I 
guess builder can help there a bit, though I don't see a way to give my 
own parser (which I need in this case).  Any suggestions about any of it 
are welcome.

The module is at: 
https://svn.openplans.org/svn/TaggerStore/trunk/taggerstore/atom.py

I didn't really look around in the lxml source, but I used several 
descriptors that could be general purpose.  Maybe there's a better way 
to do these, or maybe they could go in lxml somewhere.
