The proposed update seems reasonable to me. However, we don't have to 
make assumptions regarding how handle is generated by RDAP servers. In 
my opinion, the document should simply give guidance to RDAP 
implementers about how to disambiguate cases where overlap may occur. 
Therefore, I would change the sentence as in the following:

OLD

The server SHOULD define a scheme
for the <handle> parameter to differentiate

NEW

Where overlap may occur, the server SHOULD define a scheme
for the <handle> parameter to differentiate


Best,

Mario
