Inapplicable example 5 shouldn't be inapplicable. Inapplicable example 9 and 10 seem to me like they should fail the success criterion.

• Make sure to also review the proposed Call for Review period. In case of disagreement, the longer period wins.

Agreed. These 3 examples fail HTML page lang attribute has valid language tag and therefore 3.1.1 and shouldn't be here.
