| /* 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. |
