Not at all, I merely said that you were harsh on 
"what he was trying to achieve.

As I undestand it (and I am far from being an expert!), XSL is not
fixed enough for this to be a sensible goal at this stage. Clearly, if
XSL could call applets, then it would be Turing-complete and (in
principle!) we wouldn't worry.

True, if you assume that all bases divide a sufficiently high multiple of 10.
I think I prefer the idea of a rendered negotiating for decimal with a 
system, and letting the sytem do its conversion.
