But the description says:
It is designed to hold various types of domain names, including names used for A
or AAAA records (host names) and other records, such as SRV records.
And in DNS resource records, wilcard names are possible.
It is true that wildcards are not permitted in host names and such, but then the
"inet:host" type should not have domain-name as its member type. Even with the
existing version the "host" type permits "." which is not good either.
The "inet:host" type should IMO adhere to a stricter syntax of RFC 952. I will
send another message to address this.
