Title: Resolve SC 4.1.2 issues with Accessibility API values (technique H91)

- Text input fields where the value attribute is absent shouldn't be treated as a missing API value, since HTML 4 declares the attribute as "implied" and thus, effectively has an empty value. This is considered legal by technique H91 (see example 3b).

- Select elements should now be allowed to have zero elements selected if they are set "multiple". If they are single, a selected option must still be set, because HTML 4 declares the implementation of an empty selection as explicitly undefined.
