Comment:
The `custom:` speciefier indicates it is not SPDX. Use something along the lines of `custom:proprietary`.

The line wrap looks good, but maybe make it consistent. I.e., if you are going to split at (I think you did) 90 characters, split the next line at 90 characters too... keep all of the lines for that block the same length.
