Distracted by life  ;)

Okay, so I just did this:

162     container tls-versions {
163       description
164         "Parameters regarding TLS versions.";
165       leaf min {
166         type identityref {
167           base tls-version-base;
168         }
169         description
170           "If not specified, then there is no configured
171            minimum version.";
172       }
173       leaf max {
174         type identityref {
175           base tls-version-base;
176         }
177         description
178           "If not specified, then there is no configured
179            maximum version.";
180       }
181     }   

All good?
