By far, I think your answer is the most accurate of them all, the only thing
that I would have done to it is -
access-list 100 permit ip 200.0.3.0 0.255.0.255 255.255.255.0 0.0.0.128
That way he can get the some of the other subnets in his fourth octect.

Subject: Re: Complex Access-list
if you want to advertise 200.x.3.0, where x is any number, this would
include 200.6.3.0/25.
If you are trying to match:
200.3.3.0/24
200.4.3.0/24
200.6.3.0/25
your list should read: access-list 100 permit ip 200.0.3.0 0.255.0.0
255.255.255.0 0.0.0.128 if you X is any number.
An even more specific match to these 5 networks would be: access-list 100
permit ip 200.0.3.0 0.7.0.0 255.255.255.0 0.0.0.128
It depends how specific a range you're trying to match though. The above
list will only allow prefix lengths of /24 and /25
