I think an BCP document or implementation guide is necessary.

There are at least three points, I think.

+-----------------------+-------+------------------+----------------------
| function              ||mDNS  | DHCP             |
+-----------------------+-------+------------------+----------------------
| resolving:            || mDNS | normal DNS query via DNS proxy
| holding zones:        || mDNS | authoritative DNS server
+-----------------------++------+------------------+---------------------
| declaring client name || mDNS | DHCP client name | DNS update (directly)
+-----------------------++------+------------------+----------------------
|implementation         || mDNS |dnsmasq or DHCPD+BIND |  new
+-------------------------------------------------------------------------

mDNS requires special code to resolve the domain name. (Isn't it?)

dnsmasq has an authoritative server function in it.
