protected org.apache.xerces.xni.QNametoUpperCase(org.apache.xerces.xni.QName qname)
This method upper-cases the prefix, localpart, and rawname fields in the specified QName and returns a different QName object containing the upper-cased string values.

param
qname The QName to upper-case.

        String prefix = qname.prefix != null
                      ? qname.prefix.toUpperCase() : null;
        String localpart = qname.localpart != null
                         ? qname.localpart.toUpperCase() : null;
        String rawname = qname.rawname != null
                       ? qname.rawname.toUpperCase() : null;
        String uri = qname.uri;
        fQName.setValues(prefix, localpart, rawname, uri);
        return fQName;
