Hmm, the actual instantiation looks like invalid data. If the leaf is an
identityref with "foo-type" as its base, then permitted values are exactly those
"foo-type-[1-9]".

If the server supports a particular type, then I would expect it to implement a
module where the identity corresponding to that type is defined.
