+- functions setting CRMF Registration Info
+
+=head1 SYNOPSIS
+
+ #include <openssl/crmf.h>
+
+ int OSSL_CRMF_MSG_set1_regInfo_utf8Pairs(OSSL_CRMF_MSG *msg,
+                                          const ASN1_UTF8STRING *utf8pairs);
+ int OSSL_CRMF_MSG_set1_regInfo_certReq(OSSL_CRMF_MSG *msg,
+                                        const OSSL_CRMF_CERTREQUEST *cr);
+
+=head1 DESCRIPTION
+
+OSSL_CRMF_MSG_set1_regInfo_utf8Pairs() adds a copy of the given B<utf8pairs>
+value as utf8Pairs regInfo to the given B<msg>. See RFC 4211 section 7.1.
+
+OSSL_CRMF_MSG_set1_regInfo_certReq() adds a copy of the given B<cr> value
+as certReq regInfo to the given B<msg>. See RFC 4211 section 7.2.
+
+=head1 RETURN VALUES
+
+All functions return 1 on success, 0 on error.
+
+=head1 NOTES
+
+Calling these functions multiple times adds multiple instances of the respective
+control to the regInfo structure of the given B<msg>. While RFC 4211 expects
+multiple utf8Pairs in one regInfo structure, it does not allow multiple certReq.
