Enum Resolution 

pub enum Resolution<R> {
    Resolved(R),
    Missing,
    Unresolved,
    Unauthenticated,
    Unsupported,
}

URI lookup outcome without confusing processing refusal with absence.

Variants

Resolved(R)

An authenticated original reference was passed to the scoped visitor.

Missing

Original attribute is absent.

Unresolved

URI does not resolve to a reference in the supplied source context.

Unauthenticated

Reference is foreign or its instruction is not authenticated.

Unsupported

The XML owner’s configured mechanism cannot process this URI form.
