Dejan,

First, I would suggest you "explore" the file using ogrinfo. 
Generally speaking the only attribute linkage information that
OGR captures is the MSLink and record number for database
linkages.   DGN Features with more than one linkage end up
only presenting the first. 

If you see what you need in the ogrinfo report, then you can
use the attributes in mapserver.  If not, you are out of luck.

Best regards,
