Re: [xml] libxml2 and schema validation

Humm, yes, I think I will take a look into it.  We are using your 
library here, so it would be nice to give something back.

I am not looking at anything soon, just that I should have some extra 
time during December at work here, and will poke into what I think it 
might take.

Cheers,
Steve Williams
