The soft X-ray spectrum of the innermost regions (r < 30 arcsec) of NGC1068 as observed with the Reflection Grating Spectrometer on XMM/Newton displays a wealth of discrete features. Preliminary analysis of the spectrum indicates that the emission is completely dominated by recombination in cool, X-ray photoionized gas, with a possible contribution from emission following photoexcitation by the obscured central continuum source. We briefly discuss constraints on the properties of the emission line region derived from the spectroscopic analysis.
