The sentence "a good value is 10" seems to me indicating that it is just a possible value. The important thing is to have a limit. Do we think it should be rewritten with RFC 2119 words? MUST have a limit and the RECOMMENDED value is 10? > Section 4. > The section starts with query for "foo.bar.baz.example" and walk through refers > to a.b.example.org as query input.

One for foo.bar.baz.example and one afterwards ("Here are more detailed examples") for a.b.example.org. In the first one, ns1.nic.example is indeed used. Should we use the same QNAME for both? > Section 5 > "QNAME minimisation may also improve lookup performance for TLD > operators.

With QNAME minimisation, an authoritative name server MAY use exact matching ("do I know foobar.example?") while without it, it MUST use tree matching ("do I know thing.stuff.foobar.example or an ancestor of it?") and tree matching is typically slower.
