[xml] A big THANK YOU to the developers

[Yan Seiner <yan seiner com>]

I've just ported my embedded app to all libxml calls.  I use a 
combination of PHP and C backend.

My execute times for my longest run have dropped from about a minute to 
about 8 seconds from using the PHP expat library, the code has gone from 
spaghetti to something a mortal human can actually understand, and I've 
cut the amount of code in half.  (It's a good thing I don't get paid by 
the line, eh?)

I know this isn't said often enough, so once again, thank you everyone 
for all your work.
