KLayout stores PCell parameters in a cell called $$$CONTEXT_INFO$$$. Some foundries do not like this. You can easily remove the PCell parameters from the layout by saving it with the option "Store PCell and library context information (format specific)" turned OFF. This file will then only contain the geometries, and the link to the libraries will be removed.
It uses a cell called $$$CONTEXT_INFO$$$. In there it adds elements with "property attributes" and "property values" (essentially a dictionary of the PCell's parameters). One SREF per PCell. The text below was saved by KLayout using the save-as text option. This can be saved and loaded, and can be useful for debugging design files (and perhaps doing things like search and replace).
