  The problem is taht interfaces like xmlParseFile don't allow you
to do this !
  You need to use more advanced interfaces like the ones used in xmllint.c
where you create your own parser context:
  Look at xmllint.c code, somethings like the following should work:

    xmlParserCtxtPtr ctxt;

    xmlDoValidityCheckingDefaultValue =1;
    ctxt = xmlCreateFileParserCtxt(filename);

    xmlParseDocument(ctxt);
    ret = ctxt->wellFormed;
    valid = ctxt->valid;
    doc = ctxt->myDoc;
    xmlFreeParserCtxt(ctxt);
    if (!ret) {
        xmlFreeDoc(doc);
        doc = NULL;
    }
