Ok, I think I know the structure of the value. When I look at a "microsoft
style" request samle with the openssl command line tool, I get the following
output:
...
362:d=6 hl=2 l= 51 cons: SEQUENCE
364:d=7 hl=2 l= 9 prim: OBJECT :1.3.6.1.4.1.311.20.2
375:d=7 hl=2 l= 38 prim: OCTET STRING
415:d=3 hl=3 l= 241 cons: SEQUENCE
418:d=4 hl=2 l= 10 prim: OBJECT :1.3.6.1.4.1.311.13.2.2
430:d=4 hl=3 l= 226 cons: SET
433:d=5 hl=3 l= 223 cons: SEQUENCE
436:d=6 hl=2 l= 1 prim: INTEGER :02
439:d=6 hl=2 l= 78 prim: BMPSTRING
519:d=6 hl=3 l= 137 prim: BIT STRING
659:d=1 hl=2 l= 13 cons: SEQUENCE
661:d=2 hl=2 l= 9 prim: OBJECT :sha1WithRSAEncryption
672:d=2 hl=2 l= 0 prim: NULL
674:d=1 hl=3 l= 129 prim: BIT STRING
OpenSSL> asn1parse -in testcert.txt -strparse 375
0:d=0 hl=2 l= 36 prim: BMPSTRING
OpenSSL>
So it seems that I have to add a BMPSTRING as a subfield of the OCTET STRING.
But how can I do that?!

The way X.509 extensions work, the whole structure of the value
resides in that OCTET STRING. What you need to figure out is the
structure of the value and how to populate it. This may mean that you
have to ask Microsoft.
