If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that Work shall terminate as of the date such litigation is filed.

-     You may add Your own copyright statement to Your modifications and may provide additional or different license terms and conditions for use, reproduction, or distribution of Your modifications, or for any such Derivative Works as a whole, provided Your use, reproduction, and distribution of the Work otherwise complies with the conditions stated in this License.

-## Use as go library
-
-The modules of this repository can be used as library by other Go applications. [ISDuBA](https://github.com/ISDuBA/ISDuBA) does so, for example.
-But there is only limited support and thus it is _not officially supported_.
-There are plans to change this without a concrete schedule within a future major release, e.g. see [#367](https://github.com/gocsaf/csaf/issues/367).
-
-Initially envisioned as a toolbox, it was not constructed as a library,
-and to name one issue, exposes too many functions.
-This leads to problems like [#634](https://github.com/gocsaf/csaf/issues/634), where we have to accept that with 3.2.0 there was an unintended API change.
