/**
 * Represents a node pointer that points to a path supported by the ADK from SIF 1.x, but
 * for which there is no actual element. For Example, the GradYear/@Type attribute exists in SIF1.x,
 * but doesn't exist in SIF 2.x. FauxElementPointer could be built based on a SIF 1.x XPath, but
 * will actually point to the in-memory SIF 2.x field.
