I was skeptical of the title. How would this be different than using sexp's to define xml? I read it anyway because defmacro.org never disappoints and it didn't today either.

The concepts that he presents have been around for a very long time, but I've never seen them implemented in a way I really liked. I've already bought into this way.

1. Good use of objects. 2. The use of CSS provides a good way for customizing look and feel without diving into source code so much.

Ok, I'm seriously interested in this. Nice work!

Nice work, once again! Keep it up, Slava.
