In fact it is sort of working for many browsers. I think
that on the linux platform recents mozilla.
I found an interesting link about
testing browsers.
BTW: his was only a proof of concept. I am working on a cleaner version. The problem is not perl
but JS, DOM and, possibly, CSS. I think that perl is the best language
to generate programsm like here JS code.
But it is very difficult to find reliable information of what one can do one the real word (versus the specs).
Code repository are many but they always propose the same things.
