I could read the page
http://www.refal.net/english/doc/ark_klimov/index.html,
but I could not download
http://www.refal.net/english/doc/ark_klimov/Refal6.zip.

Yes, this one worked. But I'm afraid I will not be able to make an efficient
use of the system only with the documentation which is included in the
distribution.

I was surprised to see that the Refal-6 executables are older than that of
Refal-5. Isn't Refal developed further anymore?

Thanks for this reference.

I also thought of using a language of the ML family, but unfortunatly I've
been procrastinating to learn one of these languages for quite a long time
now, and regarding the XML transformations I need some results quite
quickly. When I found Refal, I was impressed by the simplicity and elegance
of the language.

Thanks for the offer, I possibly will approach you later regarding this.
