> If an optional requirement has at least one matching capability available to it then the resolver only lets the resource resolve if at least one of the optional candidates gives a consistent class space; otherwise the resource will fail to resolve.
> While not required by the spec to find a solution, if one exists we could modify the resolver to allow a permutation that has zero candidates for optional requirements.
