.. SPDX-License-Identifier: CC-BY-4.0 Copyright 2026 The Linux Foundation ``WITH`` Expressions ==================== Use a ``WITH`` operator to indicate that a license is subject to an *exception* or *other additional non-standalone text*. For example: ``# SPDX-License-Identifier: GPL-3.0-only WITH Autoconf-exception-3.0`` indicates that the recipient must comply with `GPL-3.0-only `__, *but* may also exercise the additional permission described in `Autoconf-exception-3.0 `__ when doing so. The ``WITH`` operator should *only* be used with language that is considered additional text appended to another standalone license. This may include exceptions that are on the `Exceptions List section of the SPDX License List `__, or with :doc:`custom AdditionRef- text `. The ``WITH`` operator should *not* be used to combine two standalone licenses. In that case, you probably want ``OR`` or ``AND`` instead.
