Wow, I can be blind some days, thanks for pointing that out; fixed. py.xml and the library he made are both interesting, I'd even use them myself, they are elegant in their own ways.
I don't really see how his code works like mine. Sure the result is the same, but that's not really relevant ;-) His code assembles the nodes of the document at run time, with mine it's predefined (but you can add to it at run time). I do like how he uses addition to assemble his documents though, it seems quite flexible. It is something I might think about adding to my own. "You will be assimilated. Resistance is futile."
