Can you explain exaclty how you'd use this from within a program? Are
you wanting to register the extension functions without their
namespaces?

    /* invalid example */
    exsltStrXpathCtxtRegister(ctxt, NULL);
    xmlXPathEval((const xmlChar *)"concat(n)", ctxt);

Now, what function is that calling?
