xmlSecTmplEncDataEnsureCipherValue() method has one parameter - pointer
to the parent EncryptedData or EncryptedKey node.

xmlSecTmplKeyInfoAddEncryptedKey () method also has first parameter -
pointer to the parent node.

Thus, get a pointer to  <env:Header> node and call
   enc_key_node = xmlSecTmplKeyInfoAddEncryptedKey(header_node, ...);
   xmlSecTmplEncDataEnsureCipherValue(enc_key_node);


Finally, you don't need to use xmlsec template functions to create
the template. You can also do it manually by calling Libxml2 functions
or load template from a file, or ....
