coerce either a parent and instance, a parent or an instance.
If there's both a parent and an instance, the instance is relative
to the parent, so resolving needs to be done by combing them
We're supporting the parent/instance combo (somewhat) but don't
really need it - <instance>/update works fine, and no instance is
required for /create
