Hi all, Continue the discussion above. I suggest modifying the first paragraph of page 26 of draft-ietf-alto-unified-props-new-01
"It is RECOMMANDED that a new ALTO entity domain be registered when the corresponding address type is registered based on ALTO Address Type Registry [RFC7285]." as the following: "When a new address type is registered in the ALTO Address Type Registry [RFC7285], the same identifier MUST be also registered in the ALTO Entity Domain Registry. And the Entity Address Encoding of this entity domain identifier MUST include both Address Encoding and Prefix Encoding of the same identifier registered in the ALTO Address Type Registry [RFC7285]." Any comment?
