| * X509_REQ_INFO is handled in an unusual way to get round invalid encodings. |
| * Some broken certificate requests don't encode the attributes field if it |
| * is empty. This is in violation of PKCS#10 but we need to tolerate it. We |
| * do this by making the attributes field OPTIONAL then using the callback to |
| * initialise it to an empty STACK. This means that the field will be |
| * correctly encoded unless we NULL out the field. As a result we no longer |
| * need the req_kludge field because the information is now contained in the |
| * attributes field: 1. If it is NULL then it's the invalid omission. 2. If |
| * it is empty it is the correct encoding. 3. If it is not empty then some |
| * attributes are present. |
