Like so?

subnet 192.168.173.0 netmask 255.255.255.0 {
     option domain-name-servers 192.168.173.10, 192.168.173.11;
     option routers 192.168.173.1;
     option ip-forwarding on;
     option broadcast-address 192.168.173.0;
     option ntp-servers 192.168.173.2;
     option netbios-name-servers 192.168.173.3;
     default-lease-time 1800;
     min-lease-time 30;
     max-lease-time 3600;
}

The 'subnet' declaration matches the 'option broadcast-address'
declaration here and when I tested the new .conf file it worked?

Should I include some error checking to ensure the subnet declaration
and the broadcast-address (if present) match?

I hope I understood you correctly.
