I think you meant "responseTTLType" instead of the second "commandTTLType" above, but that's a good spot, thanks. Fixed in my working copy.

Thanks - the domain create and info examples have been updated to include a custom RR type to demonstrate its use and also to ensure the test script catches any similar errors to the one above.

> What’s not clear in the server, is the set of <ttl> elements to return in the info response.  Should the server return only the <ttl> elements that have been explicitly set or should the server return the <ttl> elements for all support resource record types?  Inclusion of the TTL server policy attributes (“min”, “max”, and “default”)  would make the case to include all supported resource record types, which seems overkill to include in all domain and host info responses by default.  I believe it’s best to extend the info command with an <ttl:info> element that includes the option to include the policy attributes in the info response, which would also include the full set of supported resource record types with the server policy attributes.

This makes sense. I will add this into the next version.

Thanks,

G.
