I thought about that after I replied. I guess you are saying that it is conceivable for a network device to support ietf-bfd but not support routing (ietf-routing)? 

Thanks,

    Right, schema-mount can be used in some cases (logical device or in a VRF) but doesn’t have to be used in other cases (e.g. network device which doesn't support VRFs). We will clarify the text, at a certain time we incorrectly thought that schema mount had to be used in all cases.

        This is what I thought but the text is kind of misleading:
        
           BFD can operate in the following contexts:
        
           [...]
        
           The approach taken is to do a schema-mount (see Schema Mount
           [I-D.ietf-netmod-schema-mount]) of the BFD model in the appropriate
           locations.
