The simplest and most
direct method for editing xrefs is to open the source file for the
referenced drawing in a separate window. This method gives you access
to all objects in the referenced drawing.

an xref or its nested xrefs with the External References palette

edits, close the drawing, resume working and save
back edited referenced drawings in your
original drawing.
