  Then what wou really need is a 
    xmlRelaxNGSetParserErrors(xmlRelaxNGParserCtxtPtr,
                              xmlRelaxNGValidityErrorFunc *,
                              xmlRelaxNGValidityWarningFunc *,
                              void **)

function, not another field in the structure !
Right ?
