[xmlsec] creating a ds:KeyInfo object

All that I am trying to do is:
1.  Load the cert file
2.  Write the public key X509Data into a newly created KeyInfo Object

I don't want an entire Signature object with ds:Signature node.  Are
there any examples of how to write a custom KeyData Object?

I still cannot still understand what is wrong with this:
xmlSecKeyInfoNodeWrite(cur, key, keyInfoCtx)
where xmlSecKeyPtr key = xmlSecKeyCreate(); xmlNodePtr cur = NULL;

  if (xmlSecCryptoAppKeyCertLoad(key,
                                    xmlSecKeyDataFormatPem) < 0) {
     myKeyInfo =  xmlNewNode(NULL, BAD_CAST "KeyInfo");

       /* <dsig:KeyInfo/> node */
       cur = xmlSecAddChild(myKeyInfo,
       if ( xmlSecKeyInfoNodeWrite(cur,
                                   keyInfoCtx) < 0)
           printf("ERROR: writing KeyInfo Node\n");
