Enum ValiditySurface 

#[non_exhaustive]
pub enum ValiditySurface {
    Aria,
    Omit,
}

How one rendered element exposes validity.

Validity has no native spelling, so this axis has no Native variant. It gates aria-invalid and aria-errormessage together, since a validity reference without a validity state is not meaningful.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Aria

Emit aria-invalid, and aria-errormessage while invalid.

Omit

Emit neither, for roles where aria-invalid is unsupported or deprecated.
