value of measurement parameters $\vartheta_j$ and $\varphi_j$ attached to measuring apparatuses which can operate quite independent (e.g., in a spacelike separated region) from the corresponding apparatuses used to measure the spin of particles $1,2,\ldots,N,$ thus giving rise to a generic [*entangled entanglement*]{} of the kind contemplated by Krenn and Zeilinger [@KZ]. \[The dependence of the entanglement on the $\vartheta_j$’s as well as the dependence on the relative phase of $|\Psi^{+}_{12\cdots N}\rangle$ on the $\varphi_j$’s are made explicit in Eq. (27).\]
