data.xml update

[Herwig Hochleitner]

Hello Everybody,

it took me about a year and multiple failed rewrites, to admit, that keeping a compatibility mode for the current prefix-emitting hack in clojure.data.xml, is just to much of a hassle and complexity nightmare for it to be worth it.

So now, non-namespaced names are represented as plain keywords as before, but namespaced names are represented as QNames, or shorthanded to a prefixed keyword according to an aliasing mechanism, see updated http://dev.clojure.org/display/DXML/Namespaced+XML

I'm pretty happy with the resulting rewrite (https://github.com/bendlas/data.xml) and I think it's a great time now, to try it out and help sand off the edges.

Please let me know, how well this approach could support your use case for namespaced xml.

thanks
