Did some research and it looks like callbacks are possible, and I think the reason the go code won't work is because you can't send a go function pointer into a CGo call without a custom wrapper, this fella talks about a sample implementation here.

I don't understand enough about how libxml works (and my C is rusty at best), so I'm not sure if I can replicate it using C.xmlSchemaGetValidErrors(), but i think the trick is:

• Create a wrapper for C.xmlSchemaGetValidErrors and define it some C code (included with the package), call it xmlSchemaGetValidErrorsWrapper
• xmlSchemaGetValidErrorsWrapper does not need a callback parameter, instead, it calls xmlSchemaGetValidErrors directly, explicitly naming the pointer to the exported Golang function
• In the go code, call the wrapper instead of xmlSchemaGetValidErrors

I just can't figure out al the types for the wrapper function...

Just an idea, what do you think?
