/**
 * A ValidatableURI provides the unique identity of a Validatable Node which is a model node
 * and which typically forms the basis of a distinct tree node in the LH pane of the Validity View.
 * <p>
 * The ValidatableURI is simply computed by EcoreUtil.getURI(eObject), but it is convenient to
 * maintain a wrapper on the URI to reduce confusion between model and meta-model object spaces.
