Used today (yesterday, actually) to take a look over the various things that can be done when using XML and XLST together. All in all it seems very impressive, and can hugely alter the way which a document may first be formatted. This may be a valid reason to choose this method over more standard CSS techniques, which generally just alter bog standard settings like color, font-size ….
On a side note, I also managed to get an NT install of CVS sorted and working nicely on my machine. I think this will come in most handy when I finally get down to a bit of prototyping (which hopefully is the not-too-distant future).
