        <!-- This "foreign" process node is duplicated here from the corresponding sale_stock node because
             `project_mrp` implements a basic procurement system for services without actually using the
             full-fledged procurement process from sale_stock, and without the dependency. So it stil
             represents a "procurement system".
             TODO: To cleanup this invalid foreign external ID, the node should probably be moved to the
             `sale` module directly, and removed from both `sale_stock` and `project_mrp`.
