How can I add new sequences?

[NeReallly]

In the example (openssl/crypto/pkcs7/example.c)
There are add_signed_string and add_signed_seq2string functions.
How can I add sequences to make it like this:

SEQUENCE (2 elem)
              OBJECT IDENTIFIER 1.3.6.1.4.1.6801.2.8
              SET (1 elem)
                SEQUENCE (10 elem)
                  SET (1 elem)
                    SEQUENCE (2 elem)
                      OBJECT IDENTIFIER 2.5.4.3 commonName (X.520 DN component)

                  SET (1 elem)
                    SEQUENCE (2 elem)
                      OBJECT IDENTIFIER 2.5.4.4 surname (X.520 DN component)
                      UTF8String TEST
                  SET (1 elem)
                    SEQUENCE (2 elem)
                      OBJECT IDENTIFIER 2.5.4.5 serialNumber (X.520 DN component)
