 - For any DPC++-related commit, the `[SYCL]` tag should be present in the
   commit message title. To a reasonable extent, additional tags can be used
   to signify the component changed, e.g.: `[PI]`, `[CUDA]`, `[Doc]`.
+- For product changes which require modification in tests outside of the current repository
