The "namespace" defined in BIP43 is acceptable. BIP44's is no= t:

https://github.com/bitcoin/bips/blob/m= aster/bip-0044.mediawiki#Registered_coin_types

It defines a centralized registry controlld by a single comp= any instead of having a way for different companies (or p2p chains like nam= ecoin?) to maintain competing registries.

Even better, it could use a code deterministically generated= from the chain ID (the hash of the genesis block), completely removing the= need for a registry in the first place.
