Thanks Jean-Pierre.

Please wait until after I commit next.

Yes, now by readily available parsers.

I said I would do it.  It can be done using a number of strategies now. 
I might be inclined to see what Brian comes up with in python first. 
There is python, xslt, and C++ available for this.

That was not on my commitment list, but I'll take it as an endorsement
of the strategy and concepts that pave the way for future work by others.

Please note that I still am in favor of using S-expressions for our new
data files.  I think they read better, and if you go way way back to
where I first proposed using them for basically everything, I also said
we would have a round-tripper to xml that could be used by folks who
preferred to have it in XML for some external utility.

This is a special situation where I could not wait for the S-expressions
and want to involve XML tools earlier.
