O-Kay ... I went and did a closer (read: proper) comparison. And ...

About my only concern with the current XML output really concerns the choice of using CDATA vs. Attributes in various spots. However, that very topic can pretty much devolve into something close to religious debate, so I might want to steer clear of that one!

Other than that, the XML is well-formed, and non-redundant ... and completely machine-readable. This is A Good Thing^tm.

Having written that, and knowing full well the wonders of XSLT, I'm curious to know what kinds of transformations folks are seeking (if at all). Perhaps we can kick-start a collection for riocar.org or something. Suggestions welcome!

(Roger, thanks again - that you pulled this off in five minutes is in fact most laudable.)
