  We present high resolution X-ray spectra of 14 cooling-flow X-ray clusters
and groups obtained with the Reflection Grating Spectrometers (RGS) on
XMM-Newton. The spectra exhibit line emission from a number of Fe L charge
states as well as O VIII, Mg XII, Ne X, Si XIV & XIII, N VII, and C VI. All
spectra show a deficit of soft X-ray lines predicted from the isobaric
multi-phase spectral model as compared with morphological mass deposition rates
from spatially-resolved spectroscopy with the European Photon Imaging Cameras
(EPIC). We present some weak detections of plasma several times cooler than the
ambient cluster temperatures. The results further suggest that either
morphological mass deposition rates systematically overestimate the actual
cooling rate or the emission measure of cooling-flows has a much steeper
distribution than that predicted by a simple isobaric multi-phase model. We
briefly discuss some modifications to the cooling-flow process.
