I think you meant "responseTTLType" instead of the second "commandTTLType" above, but that's a good spot, thanks. Fixed in my working copy. > I have the following recommendation: > > I implemented from the full examples included in the draft, so my > recommendation is to include the use of the <ttl:ttl for=”custom” > custom=”DELEG”>3600</ttl:ttl> in the domain create and domain info response > examples to cover all > elements defined in the XML schema.

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.

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