Susan,

Many people don't know what NLRI abbreviation stands for (Network Layer Reachability Information , so writing it out first time would be a good idea. 

Throughout the text, the requirement number sequence is confusing until you get to the very and where all requirements are listed and then it makes sense.

REQ04: The ability to interact with various policies configured on
      the forwarding devices, in order to inform the policies
      implemented by the dynamic routing processes.  This interaction
      should be through existing configuration mechanisms, such as
      NETCONF, and should be recorded in the configuration of the local
      device so operators are aware of the full policy implemented in
      the network from the running configuration.
It is not clear to me if your requirement is that dynamic protocols should impose persistent policies? It says it should be recorded in the configuration of the local device.

I agree that those policies should be visible to operators and other applications, but not sure if dynamic protocols should be allowed to implement persistent policies. IMO, those should be ephemeral policies.
So maybe text should look like this
This interaction should be through existing configuration mechanisms, such as NETCONF, and should be recorded in the running or ephemeral configuration of the local device so operators are aware of the full policy implemented in the network from the running configuration.

I'm trying to see major difference between REQ01/REQ02 and REQ08/REQ09?

In general I'm not sure if changing entries by dynamic protocol in RIB is a good idea. If you plan to change only what is configured on the local device, then that is OK, but if you start changing entries that are pushed from other devices in the network, the system would get unstable. And it looks to me that REQ09 would allow that.
